Two quick observations:
(a) you connect from CUPS to the printer via IPP, and the error_log
contains an error message from the CUPS ipp backend. Maybe the
printer's IPP stack is buggy? (There are a lot of devices where
IPP support is sub-optimal, unfortunately. You can try to connect
via DEVICE_URI "socket://xxx.xxx.xxx.xxx:9100" to the printer and
see if that gives more success)
(b) you are sending PostScript to the printer, and the error_log does
not enumerate PostScript as a supported format (response of the
printer to the IPP query by the CUPS ipp backend when it asks for
the IPP attribute "document-format-supported"). Maybe the printer
indeed does not support PostScript, and you are using the wrong
driver?
What does the command
"grep cupsFilter /etc/cups/ppd/*"
return?
