Nothing new, then. :)

As before. This is the problem. I do not know the cause.

Please stop cups-browsed, edit /etc/cups/cups-browsed.conf and uncomment
"LogDir" and "DebugLogging file". Start cups-browsed and print using the
implicit class URI. Send /var/log/cups/cups-browsed_log to us and also
give the output of 'hostname' on the server.

I am cc'ing upstream cups-browsed, who might have an idea or two on why
the issue arises.

I don't have the printer, but do not need it to test most of the
printing system.
