This is lamest suggestion I've ever heard!! Are you telling me I  have 
to replace 5 printers in here because CUPS cannot properly communicate 
with them? They all worked perfectly fine with Windows NT 4.0 Server.

To the point: we have mixture of HP LaserJet 4050, 4100 and 4250 in 
here, all do that sometimes. Mostly then someone sends a 10Mb pdf file 
to the printer, or when printer runs out of paper and nobody replenish 
it. I suspect there should be some settings to tweak timeouts. I looks 
like CUPS waits for printer to respond, printer is busy doing something, 
and then printer actualy reponds CUPS already put printer into 
"disabled" mode and won't even talk to it.

What exactly Timeout parameter in the cups.conf do?
