The difference is visible, but only slightly, so the Functionality got "Mostly"<p> Do the following:<p> Set the resolution on the front panel to "Prores 1200", not to "Fastres 1200". When you use CUPS with HPs PPD file, turn off "Fastres 1200" in theprinter configuration options.<p> Try the generic PostScript PPD file which comes with KUPS 1.0 or newer.
