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.

Without avahi you have to install the printers using the CUPS webinterface on localhost:631 as remote printers (ipp protocol).

I tried that, but it did not work. Cups installs the printer but any print ends with an error (printer not available)...

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

Ok, this makes things a bit clearer:

And you can print from e.g. kate? I ask, because this does not refer to a remote CUPS printer for TDE at all. You should have some section like this in your settings:

Without avahi dnssd is not available. After removing avahi you have to delete all printers. Then install the remote pinters as IPP printers - no special drivers needed.

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.
