opensuse 11.2 deskjet 5550 stops printing

I installed opensuse 11.2 and can no longer print with deskjet 5550, printer still works perfect with opensuse 10.2 which is still on my PC in dual boot, so printer is OK.

Print jobs are accepted, a few lines are printed but then printer just stops after a few lines, power led blinking “busy”.

I upgraded hplip 3.9.8 to 3.9.12 but without succes, altough YAST shows the new driver. CUPS shows me printer failed, with paper error.
When I ‘start printer’ again in CUPS a few more lines are printed, paper ejected, paper error goes off, an new page is taken and a few lines printed, then again printer stops with error.

What can I do more?
