You have previously set up virtq and shown that the hooks are executed
correctly from the tea4cups configuration file. In other words, Tea4CUPS
does what it is designed to do; there is no bug there.
I have an HP LaserJet 2200 which has a resource path for an IPP URI that
is the same as yours. I have set up a print queue for it and have edited
printers.conf as you did. This is about as close as I can get to mimicing
your setup.
All prehooks/posthooks in my tea4cups.conf are commented out. A job sent
to the printer completes successfully, showing that tea4cups has wrapped
the backend correctly on unstable. Please try this.
For your non-printing situation, please send a complete error_log (the
wiki has advice on how to get one) compressed with xz or gzip.
Regards,
Brian.
