20 /*
21 This driver program created by Kevin M. Gift <kgift@draper.com> in Sept. 1992.
22 Modified 3/93 to correct bug in cnt_2prn size.
23 Modified 3/93 to dimension page back to 8.5, which seems to
24 work better than the actual page width of 7.6, ie. it uses
25 the full printing width of the printer.
26 It was modeled after the V2.4.1 HP Paintjet driver (gdevpjet.c)
27 Modified by L. Peter Deutsch <ghost@aladdin.com> 1999-01-10 to remove _ss
28 modifiers inappropriately copied from other code.
