Parport fifo stuck when printer out of paper

Hi,

When my parport printer runs out of paper and there are still pending print jobs, the kernel will constantly log the following:

DMA write timed out
parport0: FIFO is stuck
parport0: BUSY timeout (1) in compat_write_block_pio

To me it's pretty pointless to fill dmesg and the logfiles with this rather harmless but still annoying info.

Can this possibly be handled in a nicer way, so that the kernel keeps quiet about such minor printer issues?

Regards,
Udo.

Yes, it's debugging info. I think that FIFO/DMA printing seems to work quite well now, so maybe it's time to turn that off.
