We can test if this behaviour is independent of CUPS and the filtering
system too,
DEVICE_URI=bjnp://db-printer.fritz.box:8611 /usr/lib/cups/backend/bjnp 1 1 1 1 1 /etc/services
should churn out a few pages. It's a quick and dirty method but might
indicate whether the printer can progress beyond printing a third of a
page. The output will probably be gibberish so I'd have only 3 or 4
sheets of paper in the printer.

My misconception. I was mislead by "fritz.box" in the name.

This clears up my misconception.

Ping the printer is what I meant.

The operation panel on some printers allows printing a few sheets of
diagnostic information. If yours does, give it a try.
