Disadvantages of the hpijs-driver compared to Windows (tm) drivers + + + With the HP printer driver for Windows (tm) all capabilities of the +printer are directly usable. Photos are printable on photo paper with +best quality as well as presentation text as well as fast printouts. +There is also a toolbox which can do some special functions like print +head cleaning, show remaining ink etc. + The APDK from HP is now adopted into the hpijs-driver to make the +special functions and printmodes available with unix-systems. But the +standard mode has worse quality than the "Normal"-mode within +Windows (tm). The only modes which are really useful are the photo +modes. + +2. Improvements of this patch + + By examing the source code of the print system I tried to understand +which functions are built in that are not user accessible. My aims are +to make all three standard print modes available, to improve photo +printing even more and to implement the toolbox functions. The +standard print modes are "Draft", "Normal" and "Presentation". + First I detected that the printer uses the color pen even when printing +black text. Because of this the text printings are so bad. I changed this +for all printers except for the DJ600 when printing with a CMY-pen. + Next I started to experiment with the print modes and resolutions. I +extended the count of printer modes to 6 (0 - 5): +- Mode 0 = Grayscale mode, draft, 300 dpi (unchanged) +- Mode 1 = Normal mode, 300 dpi color, 600 dpi black/white (unchanged) +- Mode 2 = Photo mode, gossimier paper, 600 dpi color, no black (unchanged) +- Mode 3 = Presentation mode, 600 dpi color & b/w, (new) +- Mode 4 = Photo mode, gossimier paper, 1200 dpi color, no black (new) +- Mode 5 = Draft mode, 300 dpi color & b/w (new) + With these mode settings the printer can be used for paper printouts and +photos very well. I do not have additional transfer tables for the colors +so I do not know how to make modes for transparents and the other paper +types. + +3. How to use hpijs for the DeskJet 9XX-series + + The modes are dependent on the resolution settings of ghostscript! In +the following lines are examples how to use this driver with ghostscript. +Replace "InputFile.ps" by your source to print and "OutputFile.pcl" by +your desired destination filename. This file can directly be printed. Or +use ghostscript in a printing filter system. + +Mode 0 (Grayscale Mode): + gs -sDEVICE=hpijs -sDeviceName=DJ9xx -dPrintMode=0 \ + -sOutputFile=OutputFile.pcl ~/InputFile.ps + +Mode 1 (Normal Mode): + gs -sDEVICE=hpijs -sDeviceName=DJ9xx -dPrintMode=1 \ + -sOutputFile=OutputFile.pcl ~/InputFile.ps + +Mode 2 (Normal Photo Mode): + gs -sDEVICE=hpijs -r600 -sDeviceName=DJ9xx -dPrintMode=2 \ + -sOutputFile=OutputFile.pcl ~/InputFile.ps + +Mode 3 (Presentation Mode): + gs -sDEVICE=hpijs -r600 -sDeviceName=DJ9xx -dPrintMode=3 \ + -sOutputFile=OutputFile.pcl ~/InputFile.ps + +Mode 4 (Presentation Photo Mode): + gs -sDEVICE=hpijs -r1200 -sDeviceName=DJ9xx -dPrintMode=4 \ + -sOutputFile=OutputFile.pcl ~/InputFile.ps + +Mode 5 (Draft Mode): + gs -sDEVICE=hpijs -sDeviceName=DJ9xx -dPrintMode=5 \ + -sOutputFile=OutputFile.pcl ~/InputFile.ps + + +4.
