greets, everybody.
for some reason unknown to me, i can no longer print from tde apps. running localhost:631
brings up the cups admin page and i can print a test page just fine. i can print from
libreoffice and mozilla. but if i try to print from, say, kpdf, an "initializing
printing system" box pops up, then an error saying cups isn't installed or is
misconfigured.

I struggled with the same thing. My notes say this:
1) Check .trinity/share/config/tdeprintrc and ensure that it represents your CUPS server +
user account on that server. This affects any printing done from TDE
2) when printing to a remote CUPS server: delete /etc/cups/client.conf - it does bad
stuff
3) delete anything *avahi*, especially avahi-demon. If you do not, you get
"ghost" printers that do not really exist. This applies to remote pronters. Add
those with the CUPS webinterface, URI: ipp://PRINTER/printers/PRINTERNAME, Geneic,
protocol: IPP-Everywhere

Here (MX-Linux) removing avahi kills ALL printing (and reinstalling does not
help). Only restoring from backup helps.
Printers are network printers.

What does your /etc/cups/printers.conf say, after you have configured a remote ipp
printer? This is what my printer looks like:

Notice the protocol on those URLs? dnssd = DNS Service Discovery. Which
is what avahi does. Therefore, without avahi, it's no surprise your system can't
find the printers. By contrast, Nikolaus has:
DeviceURI ipp://drucker/printers/MFCJ5320DW
which is a different non-avahi protocol. I have:
DeviceURI socket://192.168.1.104
which again is not avahi-dependent.
Your setup, while not incorrect in the strict sense, is relying on automagic that's
difficult to fix when it breaks.

So if I replaced the dnssd with the DeviceURL it would work? I'll make a
backup and try when I have time.
The setup is what MX does - I just added the printers in CUPS. Just
reinstalling a printer after removing avahi does not change the way the URL
is written, so it must be something deeper un the system.
That said, avagi seems to work well here.
