must be something else.

now that I watched the issue for several days I come to the conclusion,
that it must be something with the USB stack.

The printer gives me one good printout whenever it is switched on or
unplugged from USB and replugged.
All subsequent printouts are garbage.
The type of garbage depends on the driver (tried several  PCL drivers)

tried it on different computers - same result.
common to those computers is: they run kernel 3.0.0-1-amd64

tnx for your help
