Till, could you please clarify if kinetic and lunar are fixed? It seems only cups 2.4.3[1] fixed the issue, and kinetic and lunar have 2.4.2. I checked the code in the packages with patches applied and I don't see the fix there (in kinetic and lunar).
1. https://github.com/OpenPrinting/cups/releases/tag/v2.4.3 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1971242 Title: printing PDF appears always grey, no color Status in CUPS: Fix Released Status in atril package in Ubuntu: Confirmed Status in cups package in Ubuntu: Fix Released Status in okular package in Ubuntu: Confirmed Status in cups source package in Jammy: Fix Committed Bug description: After upgrading from 20.04 LTS to 22.04 LTS I can't print colored PDF document. The print appears always b/w regardless color printing was enabled or not. Printing from LibreOffice produces a color print. This behavior (bug) is reproducible on three upgraded machines. It would be nice to have color print back again. [ Impact ] If the PPD file for a printer has a ColorModel option and the only choice in it for printing in color is not named RGB but CMYK instead, the printer cannot be made printing in color with intuitive methods, usually selcting the color choice in the print dialog (which makes ColorModel=CMYK be sent along with the job). Only an ugly command-line-based workaround, running the command lpadmin -p PRINTER -o print-color-mode-default=color makes the printer print in color. An example for printers with such PPDs are printers from RICOH and OEM (Lanier, InfoTec, Savin, ..), so many high-end color laser printers are affected. [ Test Plan ] Remove the workaround if you had applied it: lpadmin -p PRINTER -R print-color-mode-default If you have an affected printer, print a PDF file (or use the print functionality in an application) with colored content and choose the setting for color printing in the print dialog. When printing via command line do lp -d PRINTER -o ColorModel=CMYK FILE.pdf Without the SRU applied you will get a grayscale/monochrome printout, with it applied, you will get a colored printout. To test without a printer: Stop CUPS: sudo systemctl stop cups Edit /etc/cups/cups-files.conf to have a line FiileDevice Yes and start CUPS again: sudo systemctl start cups Then create a queue using the attached sample PPD file: lpadmin -p color-test -E -v file:/tmp/printout -P Ricoh- PDF_Printer-PDF.ppd Print a file to this queue as described above. When the job is done ("lpstat" does not show it any more), open /tmp/printout with a text editor. Check whether it contains a line @PJL SET RENDERMODE=COLOR near its beginning, and NOT a line @PJL SET RENDERMODE=GRAYSCALE [ Where problems could occur ] The patches are simple and they are also for some time in newer CUPS versions (2.4.2 and newer) which are included in several distributions (Ubuntu 22.10, 23.04, and others) and did not cause any complaints about color printing. So the regression potential is very low.
