If your Linux distribution does not include a version of Ghostscript with this driver, you will need to get an updated version and possibly recompile it to include the cdj850 driver.
Most Linux printing programs generate postscript. I have found that the Gnu/Aladdin Ghostscript interpreter which has drivers for older Deskjets will work with most newer deskjets, i.e. the 882C will work with the ghostscript djet500c driver, however I cannot determine how to get the full resolution of the 882C printer. What would be nice, of course, is a postscript interpreter for the newer deskjets, or at least a Ghostscript driver module. Of course, in theory any of us should be able to write one if the printer commands are available from HP.
The deskjet 8 and 9 series actually uses pcl level 3 commands, which are publically available on HP's web site, albeit under the guise of laserjet commands. Have fun :-)
