If you need to (i.e., for 9617dd7cddfSDavid du Colombieroverhead transparencies), you still can use the gamma functions, but they 9627dd7cddfSDavid du Colombierwill override the built-in calibration. To use gamma in the traditional 9637dd7cddfSDavid du Colombierway, set MasterGamma to any value greater than 1.0 and less than 10.0.

Therefore the 9727dd7cddfSDavid du Colombierdriver is not what you would expect to be a fast driver ;-) 9737dd7cddfSDavid du ColombierThis is no problem when printing a full-sized color page (because 9747dd7cddfSDavid du Colombierprinting itself is slow), but it's really annoying if you print only 9757dd7cddfSDavid du Colombiertext pages. Maybe I can optimize the code for text-only pages in a 9767dd7cddfSDavid du Colombierlater release. Right now, it is recommended to use the highest 9777dd7cddfSDavid du Colombierpossible optimisation level your compiler offers. 9787dd7cddfSDavid du ColombierFor the time being, use the cdj550 device with <b><tt>-sBitsPerPixel=3</tt></b> 9797dd7cddfSDavid du Colombierfor fast proof prints.

Note to OS/2 users: simply 9867dd7cddfSDavid du Colombierput the gs window into the background or minimize it. Also make sure that 9877dd7cddfSDavid du Colombier<b><tt>print01.sys</tt></b> is invoked without the <b><tt>/irq</tt></b> 9887dd7cddfSDavid du Colombierswitch (great speed improvement under Warp4). 9897dd7cddfSDavid du Colombier 9907dd7cddfSDavid du Colombier<p> 9917dd7cddfSDavid du ColombierThe printer default settings compensate for dot-gain by a calibrated 9927dd7cddfSDavid du Colombiercolor-transfer function.

This 14497dd7cddfSDavid du Colombierprovides the possibility, for instance, to have sharper character outlines, 14507dd7cddfSDavid du Colombierbecause you can place dots on the edges nearer to their ideal positions. 14517dd7cddfSDavid du ColombierThis is why it is worth doing. 14527dd7cddfSDavid du Colombier 14537dd7cddfSDavid du Colombier<p> 14547dd7cddfSDavid du ColombierHowever, HP will not support user-level programming of this 14557dd7cddfSDavid du Colombierresolution-enhanced mode, one reason being that (I understand) all the dot 14567dd7cddfSDavid du Colombierspacing has to be done by the driver, and if you get it wrong, you can 14577dd7cddfSDavid du Colombieractually damage the print head. 14587dd7cddfSDavid du Colombier 14597dd7cddfSDavid du Colombier<p> 14607dd7cddfSDavid du ColombierTo summarise, you may lose a smidgin of (potential) text clarity using the 14617dd7cddfSDavid du Colombier550c drivers (<b><tt>cdj550</tt></b>, <b><tt>cdjcolor</tt></b>, 14627dd7cddfSDavid du Colombier<b><tt>cdjmono</tt></b> etc.), but other than that, they are the ones for 14637dd7cddfSDavid du Colombierthe job. 14647dd7cddfSDavid du Colombier 1465*3ff48bf5SDavid du Colombier<h3><a name="HP_tips"></a>General tips</h3> 14667dd7cddfSDavid du Colombier 14677dd7cddfSDavid du Colombier<p> 14687dd7cddfSDavid du ColombierFor all the printers above, the choice of paper is critically important to 14697dd7cddfSDavid du Colombierthe final results. The printer manuals suggest type of paper, but in 14707dd7cddfSDavid du Colombiergeneral, smoother, less fibrous types give better results. In particular, 14717dd7cddfSDavid du Colombierthe special ink-jet paper can make a big difference: colours are brighter, 14727dd7cddfSDavid du Colombierbut most importantly, there is almost no colour bleed, even with adjacent 14737dd7cddfSDavid du Colombierareas of very heavy inking.

This README is about getting the printer features 1537*3ff48bf5SDavid du Colombier1-3 working with Ghostscript. No (re)compilation of Ghostscript is normally 1538*3ff48bf5SDavid du Colombierrequired. 1539*3ff48bf5SDavid du Colombier 1540*3ff48bf5SDavid du Colombier<p> 1541*3ff48bf5SDavid du ColombierGhostscript comes with a relatively highly configurable driver, called 1542*3ff48bf5SDavid du Colombier<a href="#Uniprint">uniprint</a>, for printers which understand raster 1543*3ff48bf5SDavid du Colombierimages in various propriety formats. Most options for this driver are 1544*3ff48bf5SDavid du Colombierusually organized into files having the suffix ".upp." Ghostscript 1545*3ff48bf5SDavid du Colombierversions >= 5.10 (or even earlier) include such uniprint control files 1546*3ff48bf5SDavid du Colombierfor the Canon BJC-610. They work also well for some other Canon Bubble 1547*3ff48bf5SDavid du ColombierJet models, for example for my BJC-35vII. But when using them for a 1548*3ff48bf5SDavid du ColombierBJC-8200 the result is unsatisfactory. 1549*3ff48bf5SDavid du Colombier 1550*3ff48bf5SDavid du Colombier<h3>The uniprint control files for the BJC-8200</h3> 1551*3ff48bf5SDavid du Colombier 1552*3ff48bf5SDavid du Colombier<p> 1553*3ff48bf5SDavid du ColombierAfter some experimenting with the options for uniprint I have obtained quite 1554*3ff48bf5SDavid du Colombiersatisfactory prints with my printer(*).

Other 1616*3ff48bf5SDavid du Colombieroptions, particularly the transfer arrays (-dupBlackTransfer, 1617*3ff48bf5SDavid du Colombier-dupCyanTransfer, -dupMagentaTransfer, -dupYellowTransfer) and the margins 1618*3ff48bf5SDavid du Colombier(-dupMargins) were simply copied from the files for the BJC-610, but they 1619*3ff48bf5SDavid du Colombiermay need to be changed for optimized performance. 1620*3ff48bf5SDavid du Colombier 1621*3ff48bf5SDavid du Colombier<p> 1622*3ff48bf5SDavid du ColombierHere is information useful for changing or adding uniprint control files for 1623*3ff48bf5SDavid du Colombierthe BJC-8200: 1624*3ff48bf5SDavid du Colombier 1625*3ff48bf5SDavid du Colombier<p> 1626*3ff48bf5SDavid du ColombierIn "-dupBeginPageCommand=..." use the line 1627*3ff48bf5SDavid du Colombier 1628*3ff48bf5SDavid du Colombier<blockquote> 1629*3ff48bf5SDavid du Colombier 1b28 64 0400 04b0 04b0 1630*3ff48bf5SDavid du Colombier</blockquote> 1631*3ff48bf5SDavid du Colombier 1632*3ff48bf5SDavid du Colombier<p> 1633*3ff48bf5SDavid du Colombierfor 1200x1200 resolution, and 1634*3ff48bf5SDavid du Colombier 1635*3ff48bf5SDavid du Colombier<blockquote> 1636*3ff48bf5SDavid du Colombier 1b28 64 0400 0258 0258 1637*3ff48bf5SDavid du Colombier</blockquote> 1638*3ff48bf5SDavid du Colombier 1639*3ff48bf5SDavid du Colombier<p> 1640*3ff48bf5SDavid du Colombierfor 600x600.

The unused colors are photo (or 1662*3ff48bf5SDavid du Colombierlight) cyan (c) and magenta (m). Also the Canon driver seems to use 1663*3ff48bf5SDavid du Colombieronly CMYK, for example when printing on Photo Paper Pro in "Camera" or 1664*3ff48bf5SDavid du Colombier"SuperPhoto" mode. These modes supposedly produce prints of the best 1665*3ff48bf5SDavid du Colombierquality that the Canon driver can offer. Other modes of Canon driver 1666*3ff48bf5SDavid du Colombierdo use up to all six color cartridges (CMYKcm). Therefore expanding 1667*3ff48bf5SDavid du Colombieruniprint's capabilities for six colors would be interesting, but it may 1668*3ff48bf5SDavid du Colombiernot increase the output quality of 6-color printers such as the 1669*3ff48bf5SDavid du ColombierBJC-8200 drastically. 1670*3ff48bf5SDavid du Colombier 1671*3ff48bf5SDavid du Colombier<p> 1672*3ff48bf5SDavid du ColombierMore control files for uniprint could be added in order to offer more 1673*3ff48bf5SDavid du Colombierversatility for controlling the BJC-8200 within a Ghostscript 1674*3ff48bf5SDavid du Colombierinstallation. The number of possible combinations for media type, resolution 1675*3ff48bf5SDavid du Colombierand print quality factor is very large, many combinations would not make 1676*3ff48bf5SDavid du Colombiermuch sense, many might be used here and there, but relatively rarely. The 1677*3ff48bf5SDavid du Colombieruser would have to remember a name for each combination that is used. 1678*3ff48bf5SDavid du Colombier 1679*3ff48bf5SDavid du Colombier<p> 1680*3ff48bf5SDavid du ColombierA better way would be to let the user patch optionally a user owned or 1681*3ff48bf5SDavid du Colombiersystem wide uniprint control file before each print via some print 1682*3ff48bf5SDavid du Colombiertool. This is similar to the approach taken by Canon with their driver for 1683*3ff48bf5SDavid du ColombierWindows. Similarly a uniprint tool could also incorporate other functions 1684*3ff48bf5SDavid du Colombiersuch as printing test and demo pages and the low ink warning once the 1685*3ff48bf5SDavid du Colombierprotocol for this is known. Clearly it would be difficult to code such a 1686*3ff48bf5SDavid du Colombieruniprint tool for all the platforms where Ghostscript is running. 1687*3ff48bf5SDavid du Colombier 1688*3ff48bf5SDavid du Colombier<h3>Usage on RedHat Linux</h3> 1689*3ff48bf5SDavid du Colombier 1690*3ff48bf5SDavid du Colombier<p> 1691*3ff48bf5SDavid du ColombierIn order to install a BJC-8200 printer on a RedHat Linux system with 1692*3ff48bf5SDavid du ColombierRedHat's printtool, you need also to insert with a text editor the contents 1693*3ff48bf5SDavid du Colombierof the file <b><tt>bj8.rpd</tt></b> into the RedHat printer database 1694*3ff48bf5SDavid du Colombier<b><tt>/usr/lib/rhs/rhs-printfilters/printerdb</tt></b>.

That release was also the first one to be able to use the full 17547dd7cddfSDavid du Colombierwidth of an A3 paper size. PostScript Printer Description (PPD) files for 17557dd7cddfSDavid du Colombierthe drivers were released with version 2.15. They are incomplete, 17567dd7cddfSDavid du Colombierbut they can be used to drive the printers' main features. 17577dd7cddfSDavid du Colombier 1758*3ff48bf5SDavid du Colombier<h3><a name="BJC_build"></a>Configuring and building the BJC drivers</h3> 17597dd7cddfSDavid du Colombier 1760*3ff48bf5SDavid du Colombier<h4><a name="BJC_defaults"></a>Modify values in 1761*3ff48bf5SDavid du Colombier<b><tt>gdevbjc.h</tt></b></h4> 17627dd7cddfSDavid du Colombier 17637dd7cddfSDavid du Colombier<p> 17647dd7cddfSDavid du ColombierConfigure the drivers by modifying the default values in the file 17657dd7cddfSDavid du Colombier<b><tt>gdevbjc.h</tt></b> or on the compilation line.

If you 17837dd7cddfSDavid du Colombierdefine <b><tt>BJC_DEFAULT_CENTEREDAREA</tt></b> when compiling, then the 17847dd7cddfSDavid du Colombiertop and bottom margins will be the same, resulting in a (smaller) 17857dd7cddfSDavid du Colombiervertically centered imageable area also. 17867dd7cddfSDavid du Colombier 1787*3ff48bf5SDavid du Colombier<h4><a name="BJC_margins"></a>Page margins</h4> 17887dd7cddfSDavid du Colombier 17897dd7cddfSDavid du Colombier<p> 17907dd7cddfSDavid du ColombierIf you define <b><tt>USE_RECOMMENDED_MARGINS</tt></b>, then the top and 17917dd7cddfSDavid du Colombierbottom margins will be the same (that is, 17927dd7cddfSDavid du Colombier<b><tt>BJC_DEFAULT_CENTEREDAREA</tt></b> will be defined for you) and the 17937dd7cddfSDavid du Colombiermargins will be the 12.4mm recommended by Canon. Since margins are 17947dd7cddfSDavid du Colombiercomplicated (because one must rely on the mechanical precision of the 17957dd7cddfSDavid du Colombierprinter), the drivers do something about the bottom margin: by default the 17967dd7cddfSDavid du Colombierbottom margin is 9.54mm for the BJC-600 driver and 7mm for the BJC-800. If 17977dd7cddfSDavid du Colombieryou define <b><tt>USE_TIGHT_MARGINS</tt></b>, then the bottom margin is 7mm 17987dd7cddfSDavid du Colombierfor both drivers (but I never managed to get my own BJC-600 to print a line 17997dd7cddfSDavid du Colombieron this low bound, hence the larger default). Regardless of the presence 18007dd7cddfSDavid du Colombierof this definition, <b><tt>USE_FIXED_MARGINS</tt></b> will not allow the 18017dd7cddfSDavid du ColombierBJC-800 to use the lower 7mm bottom margin, so if you have a problem with 18027dd7cddfSDavid du Colombierthe bottom margin on a BJC-800, just define that (without defining 18037dd7cddfSDavid du Colombier<b><tt>USE_TIGHT_MARGINS</tt></b>, of course). 18047dd7cddfSDavid du Colombier 18057dd7cddfSDavid du Colombier<p> 18067dd7cddfSDavid du ColombierA quick way to be sure the margins you selected is to print a file whose 18077dd7cddfSDavid du Colombiercontents are: 18087dd7cddfSDavid du Colombier 18097dd7cddfSDavid du Colombier<blockquote><b><tt> 18107dd7cddfSDavid du Colombier%!<br> 18117dd7cddfSDavid du Colombierclippath stroke showpage 18127dd7cddfSDavid du Colombier</tt></b></blockquote> 18137dd7cddfSDavid du Colombier 18147dd7cddfSDavid du Colombier<p> 18157dd7cddfSDavid du ColombierIf the margins are okay, you will get a rectangle visibly surrounding 18167dd7cddfSDavid du Colombierthe printable area.

This initiated the transformation of the 29887dd7cddfSDavid du Colombier<b><tt>stcolor</tt></b> driver into a framework for different dithering 29897dd7cddfSDavid du Colombieralgorithms, providing a generalized interface to the internal Ghostscript 29907dd7cddfSDavid du Colombiercolor models and the other data structures related to Ghostscript drivers. 29917dd7cddfSDavid du Colombier 29927dd7cddfSDavid du Colombier<p> 29937dd7cddfSDavid du ColombierThe main thing such a framework should be able to do is to deliver the 29947dd7cddfSDavid du Colombiervalues the dithering algorithm needs; and since this directly influences 29957dd7cddfSDavid du Colombierthe optical image impression, this transformation should be adjustable 29967dd7cddfSDavid du Colombierwithout the need for recompilation and relinking.

So any color 30437dd7cddfSDavid du Colombieradjustment should take place before this step and this is where the optional 30447dd7cddfSDavid du Colombier<b><tt>ColorAdjustMatrix</tt></b> works. 30457dd7cddfSDavid du Colombier 30467dd7cddfSDavid du Colombier<p> 30477dd7cddfSDavid du ColombierThe first transformation step, called "coding", is controlled by the 30487dd7cddfSDavid du Colombier<b><tt>?coding</tt></b> arrays. The decoding process expands the range of 30497dd7cddfSDavid du Colombiervalues expontentially to a larger range than that provided by the initial 30507dd7cddfSDavid du ColombierGhostscript color model, and is therefore a reasonable place to make 30517dd7cddfSDavid du Colombierdevice- or algorithm-specific adjustments. This is where the 30527dd7cddfSDavid du Colombier<b><tt>?transfer</tt></b> arrays are used. Array access might be not the 30537dd7cddfSDavid du Colombierfastest method, but its generality is superior, so this step is always 30547dd7cddfSDavid du Colombierbased upon internally algorithm-specific array access. If 8 bits are stored 30557dd7cddfSDavid du Colombierper color component and if the algorithm uses bytes too, the second 30567dd7cddfSDavid du Colombiertransformation is included within the first, which saves significant 30577dd7cddfSDavid du Colombiercomputation time when printing the data. 30587dd7cddfSDavid du Colombier 3059*3ff48bf5SDavid du Colombier<h3><a name="STC_CAM"></a><b><tt>ColorAdjustMatrix</tt></b></h3> 30607dd7cddfSDavid du Colombier 30617dd7cddfSDavid du Colombier<p> 30627dd7cddfSDavid du ColombierThe driver supports different values for <b><tt>ProcessColorModel</tt></b>, 30637dd7cddfSDavid du Colombierwhich raises the need for different color adjustments.

If no coding array is given, this is accomplished 34067dd7cddfSDavid du Colombierby dividing by 4096, equivalent to a right shift by 12 bits. The 34077dd7cddfSDavid du Colombierfinal ink density resides in the given interval and moves from the left to 34087dd7cddfSDavid du Colombierthe right side from 0 to 15. For magenta there is a coding array 34097dd7cddfSDavid du Colombierand the ink value matches the center of the intervals.

There is no linear correspondence between 36487dd7cddfSDavid du Colombierthe color and the ink values: this correspondence is defined through the 36497dd7cddfSDavid du Colombiergiven array. In other words, the transfer arrays define a nonlinear ink 36507dd7cddfSDavid du Colombiercharacteristic, which is exactly the same functionality that PostScript's 36517dd7cddfSDavid du Colombier"(color)transfer" function provides. 36527dd7cddfSDavid du Colombier 36537dd7cddfSDavid du Colombier<p> 36547dd7cddfSDavid du ColombierWhile for yellow the intervals match the intervals used with cyan, for 36557dd7cddfSDavid du Colombierblack the intervals match the magenta intervals. But watch the 36567dd7cddfSDavid du Colombiercorrespondence between the CI/15 values and the ink density for black: this 36577dd7cddfSDavid du Colombieris a linear distribution in the ink domain. 36587dd7cddfSDavid du Colombier 36597dd7cddfSDavid du Colombier<p> 36607dd7cddfSDavid du ColombierNot a bad idea, I think. Consider the <b><tt>fs2</tt></b> algorithm: it 36617dd7cddfSDavid du Colombieruses values in the range 0 to 255. If any transfer array were alone, some 36627dd7cddfSDavid du Colombierof the 256 possible values would never be used and others would be used for 36637dd7cddfSDavid du Colombieradjacent intervals several times. Establishing an identical coding array 36647dd7cddfSDavid du Colombiersolves this problem, so the full potential of the algorithm is used. 36657dd7cddfSDavid du Colombier 36667dd7cddfSDavid du Colombier<p> 36677dd7cddfSDavid du ColombierAnother useful feature of the coding arrays is that they are internally 36687dd7cddfSDavid du Colombiernormalized to the range 0-1. In 720x720dpi mode the transfer arrays in 36697dd7cddfSDavid du Colombier<b><tt>stcolor.ps</tt></b> limit the dot density to about 50%, so these 36707dd7cddfSDavid du Colombierarrays end at 0.5 (and begin at 0.5 for RGB). Because of automatic 36717dd7cddfSDavid du Colombiernormalization, these arrays can also be used as coding arrays. But of 36727dd7cddfSDavid du Colombiercourse in the <b><tt>fs2</tt></b> case mentioned above, values from 0 to 36737dd7cddfSDavid du Colombier127 will never be delivered to the algorithm, while values 128-255 are 36747dd7cddfSDavid du Colombierdelivered for adjacent intervals. 36757dd7cddfSDavid du Colombier 36767dd7cddfSDavid du Colombier<p> 36777dd7cddfSDavid du ColombierTo clarify the intended use of the three parameters (parameter groups), keep this in mind: 36787dd7cddfSDavid du Colombier 36797dd7cddfSDavid du Colombier<blockquote><ul> 36807dd7cddfSDavid du Colombier<li><b><tt>ColorAdjustMatrix</tt></b> is never used when transferring gray 36817dd7cddfSDavid du Colombiervalues.

This makes four "logical" heads, one for each color component. 37027dd7cddfSDavid du ColombierEach of these four heads has several jets at some vertical (Y) distance 37037dd7cddfSDavid du Colombierfrom one another, so several horizontal lines can be printed of a given 37047dd7cddfSDavid du Colombiercolor during one pass of the heads. From experience I think there are 37057dd7cddfSDavid du Colombierfifteen jets per color, spaced at 1/90in. 37067dd7cddfSDavid du Colombier 37077dd7cddfSDavid du Colombier<p> 37087dd7cddfSDavid du ColombierSo the question arises of how to print at a Y resolution of 360dpi with 37097dd7cddfSDavid du Colombier90dpi jets. Simply by division one gets 360dpi/90dpi = 4, which tells us 37107dd7cddfSDavid du Colombierthat 4 passes of the head assembly are needed to achieve a Y resolution of 37117dd7cddfSDavid du Colombier360dpi. 37127dd7cddfSDavid du Colombier 37137dd7cddfSDavid du Colombier<p> 37147dd7cddfSDavid du ColombierWeaving is the method of how the fifteen jets are used to print adjacent

In addition to that, for 720dpi eight passes are 39057dd7cddfSDavid du Colombierrequired, and the amount of buffer space needed to buffer the data for the 39067dd7cddfSDavid du Colombierpasses is far beyond the printer's memory. <b><tt>Softweave</tt></b> 39077dd7cddfSDavid du Colombierrequires an odd value of "<b><tt>escp_Band</tt></b>"; the Stylus Color 39087dd7cddfSDavid du Colombierprovides fifteen for that. 39097dd7cddfSDavid du Colombier 39107dd7cddfSDavid du Colombier<p> 39117dd7cddfSDavid du Colombier"<b><tt>OutputCode</tt></b>" controls the encoding used.

With the Stylus Color, Epson introduced some new encoding 39167dd7cddfSDavid du Colombierprinciples, namely "tiff" and "deltarow". While the first was omitted from 39177dd7cddfSDavid du Colombierthis driver for lack of apparent advantages, "<b><tt>deltarow</tt></b>" is 39187dd7cddfSDavid du Colombieravailable as an option. "<b><tt>Softweave</tt></b>" cannot be used with 39197dd7cddfSDavid du Colombierthis encoding, so if <b><tt>OutputCode=deltarow</tt></b> is set, 39207dd7cddfSDavid du Colombier<b><tt>Microweave</tt></b> becomes the default.

Thus 51107dd7cddfSDavid du Colombiermultiple pins or nozzles are transferred with a single command, and of 51117dd7cddfSDavid du Colombiercourse such a command must be supported by the device. 51127dd7cddfSDavid du Colombier 51137dd7cddfSDavid du Colombier</ul> 51147dd7cddfSDavid du Colombier 51157dd7cddfSDavid du Colombier<p> 51167dd7cddfSDavid du ColombierIf no other weave parameters are given, <b><tt>uniprint</tt></b> computes 51177dd7cddfSDavid du Colombierseveral defaults which together do no weaving.

Usually you can find this out from the printer manual, or the printer 5616*3ff48bf5SDavid du Colombiersupplier, but you may have to dissect a couple of printer output files 5617*3ff48bf5SDavid du Colombierproduced with the driver supplied with the printer. There is a utility 5618*3ff48bf5SDavid du Colombiercalled escp2ras<a href="#escp2ras"><sup>*</sup></a> that will help with that. 5619*3ff48bf5SDavid du ColombierSometimes the term pin is used instead of nozzle but they mean the same thing. 5620*3ff48bf5SDavid du Colombier<p>The number of nozzles will be the value assigned to the upOutputPins 5621*3ff48bf5SDavid du Colombierparameter. 5622*3ff48bf5SDavid du Colombier<p>Actually you don't have to print with all the pins available but for 5623*3ff48bf5SDavid du Colombierthe purpose of demonstration I'll assume that we are using them all. 5624*3ff48bf5SDavid du Colombier<p> 5625*3ff48bf5SDavid du Colombier<a name="escp2ras"></a>* escp2ras is available from Gunther Hess' page at <a href="http://www-md.e-technik.uni-rostock.de/ma/gunther/gs/index.html">http://www-md.e-technik.uni-rostock.de/ma/gunther/gs/index.html</a> 5626*3ff48bf5SDavid du Colombier</li> 5627*3ff48bf5SDavid du Colombier<p> 5628*3ff48bf5SDavid du Colombier<li><b>Determine how many passes are required (upWeaveYPasses)</b> 5629*3ff48bf5SDavid du Colombier<p>The number of passes required is going to depend on the required resolution 5630*3ff48bf5SDavid du Colombierand the nozzle spacing. 5631*3ff48bf5SDavid du Colombier<blockquote> 5632*3ff48bf5SDavid du Colombier<tt>passes = resolution * nozzle spacing 5633*3ff48bf5SDavid du Colombier</tt> 5634*3ff48bf5SDavid du Colombier</blockquote> 5635*3ff48bf5SDavid du ColombierThis will be the value assigned to the upWeaveYPasses parameter. 5636*3ff48bf5SDavid du Colombier<p>For example if the desired resolution is 360 dpi and the nozzles are 5637*3ff48bf5SDavid du Colombierspaced at 1/90in then 360 * 1/90 = 4 passes are required. For 720 dpi 8 5638*3ff48bf5SDavid du Colombierpasses would be required. The printer would, of course, have to be capable 5639*3ff48bf5SDavid du Colombierof moving the paper in increments of either 360 or 720 dpi too. 5640*3ff48bf5SDavid du Colombier</li> 5641*3ff48bf5SDavid du Colombier<p> 5642*3ff48bf5SDavid du Colombier<li> 5643*3ff48bf5SDavid du Colombier<b>Determine the normal Y feed increment (upWeaveYFeeds)</b> 5644*3ff48bf5SDavid du Colombier<p> 5645*3ff48bf5SDavid du ColombierYou need to work out how much to feed the paper so that when the paper 5646*3ff48bf5SDavid du Colombierhas moved by one head length in however many passes you have then each 5647*3ff48bf5SDavid du Colombierrow space on the paper has been passed over by at least one nozzle. There 5648*3ff48bf5SDavid du Colombierwill be one feed value for each pass and the feed values must comply with 5649*3ff48bf5SDavid du Colombierthe following rules: 5650*3ff48bf5SDavid du Colombier<blockquote> 5651*3ff48bf5SDavid du Colombier<tt> 5652*3ff48bf5SDavid du Colombier<p>sum of feeds = passes * nozzles 5653*3ff48bf5SDavid du Colombier<br>feed%passes != 0 (feed is not exactly divisible by passes) 5654*3ff48bf5SDavid du Colombier<br>sum of (nozzles - feed) = 0 5655*3ff48bf5SDavid du Colombier</tt> 5656*3ff48bf5SDavid du Colombier</blockquote> 5657*3ff48bf5SDavid du Colombier<p>For example if passes=4 and nozzles=15, then sum of feeds=60.

The number of nozzles would probably be be a good place 5666*3ff48bf5SDavid du Colombierto start. 5667*3ff48bf5SDavid du Colombier<p>Remember that if the number of passes is more than 1 then the feed increment 5668*3ff48bf5SDavid du Colombierwill be less than the nozzle spacing and <tt>passes × feed increment size</tt> 5669*3ff48bf5SDavid du Colombiermust equal the physical distance between each nozzle. 5670*3ff48bf5SDavid du Colombier</li> 5671*3ff48bf5SDavid du Colombier<p> 5672*3ff48bf5SDavid du Colombier<li> 5673*3ff48bf5SDavid du Colombier<b>Determine the beginning of page pins (upWeaveInitialPins)</b> 5674*3ff48bf5SDavid du Colombier<p> 5675*3ff48bf5SDavid du ColombierThese values will be assigned to the upWeaveInitialPins parameter and are 5676*3ff48bf5SDavid du Colombierthe numbers of nozzles to operate in each of the initial passes at the top 5677*3ff48bf5SDavid du Colombierof a page. The nozzles that the values refer to are the topmost nozzles 5678*3ff48bf5SDavid du Colombieron the head, nearest the top margin. If the image doesn't start at the 5679*3ff48bf5SDavid du Colombiertop margin then uniprint doesn't use these feeds. 5680*3ff48bf5SDavid du Colombier<p>I don't know a mathematical relation for this except that at least one 5681*3ff48bf5SDavid du Colombierof the values must be the number of nozzles, but I'm sure that there must 5682*3ff48bf5SDavid du Colombierbe one. I used a graphical method, the description that follows refers 5683*3ff48bf5SDavid du Colombierto the ascii diagram in below. 5684*3ff48bf5SDavid du Colombier<p>Draw a line of nozzles for each pass arranged as they would be using 5685*3ff48bf5SDavid du Colombierthe normal Y feed increment determined in step 3. In the diagram below 5686*3ff48bf5SDavid du Colombierthis would be passes 5-8. 5687*3ff48bf5SDavid du Colombier<p>Draw a line of nozzles that would print just before the first normal 5688*3ff48bf5SDavid du Colombierpass. The feed increment for this pass will be close to and most likely 5689*3ff48bf5SDavid du Colombier1 or 2 units less than the feed increment of the last normal pass. In the 5690*3ff48bf5SDavid du Colombierexample below this line is pass 4 and the feed increment is 13 whereas 5691*3ff48bf5SDavid du Colombierthe normal feed increment is 15. 5692*3ff48bf5SDavid du Colombier<p>Draw each pass before that with a small feed increment so that if all 5693*3ff48bf5SDavid du Colombierof the nozzles appearing above the first nozzle of the first normal pass 5694*3ff48bf5SDavid du Colombieroperate then all of the spaces will be filled. This feed increment is usually 5695*3ff48bf5SDavid du Colombier1 except in cases where some jiggery pokery is going on to make the printer 5696*3ff48bf5SDavid du Colombierprint at an apparent higher resolution than the nozzle diameter. 5697*3ff48bf5SDavid du Colombier<p>Now select the nozzles that will operate in each of theses initial passes 5698*3ff48bf5SDavid du Colombierso that the paper is filled. In each pass the nozzles must be adjacent 5699*3ff48bf5SDavid du Colombierto each other and at least one of the passes will have all the nozzles 5700*3ff48bf5SDavid du Colombieroperating. I suspect that for each combination of normal Y feed increments 5701*3ff48bf5SDavid du Colombierthere will only be one set of valid beginning of page increments. 5702*3ff48bf5SDavid du Colombier</li>

contributed by Glenn Ramsey.<p> 5879*3ff48bf5SDavid du ColombierThe Epson Stylus Color 300 uses a different command set to other Epson 5880*3ff48bf5SDavid du ColombierStylus Color printers that use the ESC/P2 language. As far as I can 5881*3ff48bf5SDavid du Colombiertell its commands are a subset of ESC/P2. In ESC/P2 the colour to be 5882*3ff48bf5SDavid du Colombierprinted is selected by a 'set colour' command and then the data sent 5883*3ff48bf5SDavid du Colombieris only printed in that colour until the colour is changed with another 5884*3ff48bf5SDavid du Colombier'set colour' command. The Stylus Color 300 lacks this functionality. 5885*3ff48bf5SDavid du ColombierThe data sent to the printer maps directly to the ink nozzles and colour 5886*3ff48bf5SDavid du Colombierof an output scan line in the printed output is determined by the position 5887*3ff48bf5SDavid du Colombierof the scan line within the data. This means that the driver must know 5888*3ff48bf5SDavid du Colombierhow the nozzles are arranged and must format the output accordingly. 5889*3ff48bf5SDavid du ColombierThe extension adds a format that I have called EscNozzleMap and adds some 5890*3ff48bf5SDavid du Colombier additional parameters to uniprint.<br> 5891*3ff48bf5SDavid du Colombier<ul> 5892*3ff48bf5SDavid du Colombier

Due to a problem with the device driver (in the kernel) 63127dd7cddfSDavid du Colombierthe reason for printer failure isn't always reported correctly to the 63137dd7cddfSDavid du Colombierprogram. This is the case, for instance, if you open the top cover (error 63147dd7cddfSDavid du ColombierE5 on the printer's display). Look at the display on the printer itself if 63157dd7cddfSDavid du Colombiera "Printer problem with unknown reason" is reported. Fatal errors cause 63167dd7cddfSDavid du Colombierthe print job to be terminated. 63177dd7cddfSDavid du Colombier 63187dd7cddfSDavid du Colombier<hr> 63197dd7cddfSDavid du Colombier 6320*3ff48bf5SDavid du Colombier<h2><a name="Apple"></a>Apple dot matrix printer</h2> 63217dd7cddfSDavid du Colombier 63227dd7cddfSDavid du Colombier<p> 63237dd7cddfSDavid du ColombierThis section was contributed by Mark Wedel 63247dd7cddfSDavid du Colombier<<a href="mailto:master@cats.ucsc.edu">master@cats.ucsc.edu</a>>. 63257dd7cddfSDavid du Colombier 63267dd7cddfSDavid du Colombier<p> 63277dd7cddfSDavid du ColombierThe Apple Dot Matrix Printer (DMP) was a parallel predecessor to the 63287dd7cddfSDavid du ColombierImagewriter printer. As far as I know, Imagewriter commands are a superset 63297dd7cddfSDavid du Colombierof the Dot Matrix printer's, so the driver should generate output that can 63307dd7cddfSDavid du Colombierbe printed on Imagewriters. 63317dd7cddfSDavid du Colombier 63327dd7cddfSDavid du Colombier<p> 63337dd7cddfSDavid du ColombierTo print images, the driver sets the printer for unidirectional printing 63347dd7cddfSDavid du Colombierand 15 characters per inch (cpi), or 120dpi. It sets the line feed to 1/9 63357dd7cddfSDavid du Colombierinch. When finished, it sets the printer to bidirectional printing, 63367dd7cddfSDavid du Colombier1/8-inch line feeds, and 12 cpi. There appears to be no way to reset the 63377dd7cddfSDavid du Colombierprinter to initial values. 63387dd7cddfSDavid du Colombier 63397dd7cddfSDavid du Colombier<p> 63407dd7cddfSDavid du ColombierThis code does not set for 8-bit characters (which is required). It also 63417dd7cddfSDavid du Colombierassumes that carriage return-newline is needed, and not just carriage 63427dd7cddfSDavid du Colombierreturn. These are all switch settings on the DMP, and I have configured 63437dd7cddfSDavid du Colombierthem for 8-bit data and carriage return exclusively. Ensure that the Unix 63447dd7cddfSDavid du Colombierprinter daemon handles 8-bit (binary) data properly; in my SunOS 4.1.1 63457dd7cddfSDavid du Colombier<b><tt>printcap</tt></b> file the string "<b><tt>ms=pass8,-opost</tt></b>" 63467dd7cddfSDavid du Colombierworks fine for this. 63477dd7cddfSDavid du Colombier 63487dd7cddfSDavid du Colombier<p> 63497dd7cddfSDavid du ColombierFinally, you can search <b><tt>devdemp.c</tt></b> for 63507dd7cddfSDavid du Colombier"<b><tt>Init</tt></b>" and "<b><tt>Reset</tt></b>" to find the strings that 63517dd7cddfSDavid du Colombierinitialize the printer and reset things when finished, and change them to 63527dd7cddfSDavid du Colombiermeet your needs. 63537dd7cddfSDavid du Colombier 63547dd7cddfSDavid du Colombier<!-- [2.0 end contents] ==================================================== --> 63557dd7cddfSDavid du Colombier 63567dd7cddfSDavid du Colombier<!-- [3.0 begin visible trailer] =========================================== --> 63577dd7cddfSDavid du Colombier<hr> 63587dd7cddfSDavid du Colombier 6359*3ff48bf5SDavid du Colombier<p> 6360*3ff48bf5SDavid du Colombier<small>Copyright © 1996, 2000 Aladdin Enterprises. 6361*3ff48bf5SDavid du ColombierAll rights reserved.</small> 63627dd7cddfSDavid du Colombier 63637dd7cddfSDavid du Colombier<p> 6364*3ff48bf5SDavid du Colombier<small>This file is part of AFPL Ghostscript.
