I suspect this problem is caused by this issue (https://github.com/OpenPrinting/cups/pull/500) that is fixed in cups where the option print-color-mode is set to monochrome when the printer PPD file has ColorModel: CMYK and not ColorModel: RGB (Our Ricoh C4500 uses CMYK as its ColorModel: CMYK)
We were trying to use lpadmin -p <printername> -o print-color-mode-default=colour lpadmin -p <printername> -o print-color-mode=colour and this worked the first time we printed to the printer and then it would reset to "monochrome" which I suspect is caused by this reported typo: https://github.com/OpenPrinting/cups/pull/687 Cheers, Ian. -- 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: New Status in atril package in Ubuntu: Confirmed Status in cups package in Ubuntu: Confirmed Status in okular package in Ubuntu: Confirmed 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.
