HP DeskJet 855C 600 600 51645A (Black); 51641A (Color) http://www.hp.com/cposupport/prodhome/dj855c.html us-ascii PCL,MLC,PML Hewlett-Packard Deskjet 850C HEWLETT-PACKARD DESKJET 850C A hpijs To get its maximum quality, use the "hpijs" driver, since HPIJS 1.2 there is explicit support for this printer. 600 dpi in colour is not supported by the hardware.<p> David Suffield, developer of HPIJS at HP, said about the HPIJS 1.1 driver:<p> <i>"hpijs" (set up as for the DeskJet 600 series) works for the Deskjet 850 series, much better than GIMP-Print, but color was not as good as with "cdj850". Some people may prefer "cdj850" for color, others may prefer "hpijs" for the speed.</i><p> The "cdj850" driver is included with Ghostscript as of Ghostscript version 6.0.<p> Printhead alignment is not supported.<p> A user told that he thinks there is a separate tool for alignment floating around, but unfortunately, we do not have any URL.<p>
