Good idea, thanks. When I stopped lp daemon (/etc/init.d/lpd stop) syslog
said:

Nov 20 13:39:47 q kernel: parport0: BUSY timeout (-4) in
compat_write_block_pio

and message stopped. But when i restart lpd it said:

Nov 20 13:40:25 q lpd[3569]: restarted

and than...

Nov 20 13:40:36 q kernel: DMA write timed out
Nov 20 13:40:36 q kernel: parport0: BUSY timeout (1) in
compat_write_block_pio

Now I have installed cups and problems seems solved. But, what are causes?

Glad it works for you as well. I have no idea what the cause might be
and I unfortunately don't have time to look into it any further.
Perhaps you can log a bug report on the lpr package?

But then you would need to be able to provide more information about
our specific setups. With this little information I don't see how the
(upstream) developpers would be able to know where to start looking.

I am however more than willing to provide more information if needed
so if you do create a bug report feel free to CC me.

Regards
