Taking a look at the bootlog obtained from journalctl -b, I discovered a report of the following failure:

What is EDID?  Why is it too small and how big should it be, whatever it is? Is there a programming error anywhere?
The printer itself is powered, connected to the computer via a USB cable, and in a deep sleep with all LEDs off (but if you send a there document, it wakes up).
I use Debian stable “bookworm” with udev 252.6-1  and systemd 252.6-1.

In the meantime, systemd and udev have been upgraded to version 252.12-1~deb12u1 on a similar (but not identical) computer running Debian 12 stable. There, this message seems to be unconnected to printers (because no printer is physically attached, and the only network printer is off). The relevant portion of the log is attached. I have not noticed any color issues so far. (Exception: my network printer – usually and now it's turned off – runs out of ink from time to time, but Linux knows nothing about this.)
