This is independent of lp or LibreOffice.
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. > Of course I switched the printer on and off - that didn't change > anything.

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