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 report
typo: https://github.com/OpenPrinting/cups/pull/687
Cheers,
Ian.
PS Failed to note this was a duplicate bug before posting. Apologies.
And I see it is already know in #1971242 that the latest version of cups
fixes the issue

Title:
Since upgrade from 20.04 → 22.04 ; unable to print in color, only
black and white
Status in cups-filters package in Ubuntu:
Confirmed
Bug description:
Hi,
Printer ( in my context ) is Ricoh Aficio mpc 3002 and most Ricoh's
drivers are open-source (
https://www.openprinting.org/printer/Ricoh/Ricoh-Aficio_MP_C3002 )
Since I « upgraded » my installation from 20.04 → 22.04, I'm unable to
print in colors, only black and white, whatever I set in driver.
I tried what's suggested in

https://discourse.ubuntubudgie.org/t/22-04-unable-to-add-printer-which-perfectly-worked-in-20-04/6209
I might go wrong somewhere cause I still can't manage to print in color.
→ the snap thing ( Gutenprint Printer Application ) does not detect my (
network ) printer,
→ I'm not sure of the name for PRINTER I should input in command « lpadmin -p
PRINTER -o print-color-mode-default=color » ( and is this as normal user or
sudo ? )
It seems related to

It's a regression ( as it used to work out of the box before 22.04 ).
