HP DeskJet 812C 600 600 C1823 (CMY) and C6615A (K) http://www.hp.com/cposupport/eschome.html us-ascii MLC,PCL,PML Hewlett-Packard DeskJet 810C HEWLETT-PACKARD DESKJET 810C A hpijs To get its maximum quality, use the "hpijs" driver.<p> User report:<p> Colour resolution under Linux is 600x600 dpi. HP claims the Windows driver they ship with the printer enhances this using <a href="http://www.hp.com/all-in-one/products/1170-faqs.html#faq7">"PhotoRet II"</a> technology. The driver basically changes the amount of colors per dot by reducing the size of the inkdrops. Supposedly the inkdrops are 70% smaller per dot than those produced by the average DeskJet. After checking their site, I found no driver to enable this same technology under any UNICES. Still, this should be a nice printer overall under Linux, so unleash that GIMP! This printer appears to be functionally identical to the DeskJet 810C. I am currently using the 300dpi DeskJet 550C colour GhostScript setup as shipped with Red Hat Linux 6.0, and the output is excellent in every respect. I have marked the suggested driver as cdj880 as I am 99.9% certain it will work and this driver should give the best output. <p> Good output should also be possible from the "pcl3"/"hpdj" drivers.<p> I believe that various papers like transparency, glossy, etc, are supported by one or the other "cdjXXX" driver.
