Here the output. The printer is accepted and works at this moment. 
Current kernel is 2.6.9, don't know if the failure still exists though i 
 am using it just for about 2 hours yet and until the mistake almost 1 
day has gone. I will tell immediatly if the error doesn't come up again. 
If someone needs some more information just tell me.

Thanks for response
