Bonjour,

I have several computers at home and one with an usr-printer attached.

I struggled sometimes to configure cups on other computers to use this
printer. Now I upgraded to f34, and the configuration no longer works:
"printer is misconfigured or no longer exists" is the answer if I send a
test page....

After deleting the printer, I try to use the discovery tool in the
administration page of cups (localhost:631) and it find the printer
attached to my main computer but at the end of the configuration, when I
try to print a test page, the answer is the same:
"printer is misconfigured or no longer exists"

Saying CUPS is the worst software is like saying my dead horse is the
worse horse.

CUPS is no longer the "Swiss Army Knife" of printing.  It is still used
"under the hood", but the end of PPD support was announced over
a year ago <https://www.theregister.com/2020/10/15/apple_cups_develoment/>.
Apple CUPS development seems to have ended, but there is a fork. Going
forward IPP Everywhere <https://www.pwg.org/ipp/everywhere.html>
(intended to support printing without drivers and originated to support
mobile devices), is proposed to replace the use of PPD's.   I'm not sure
where this leaves legacy printers that pre-date IPP Everywhere.
