Excuse me, I should look _all_ your patch ;-).
Basically your patch request the printer irq a lot before starting to
print. It doesn' t change how the lp handle the interrupt. This make no
sense to me. Also if this is true it means that in the parport code we
can' t request_irq/free_irq during the printing and so a lot of parport
code should be rewritten to handle that. I think also my fix can' t help
you. It would be nice if you could try the plain 2.1.98 lp and feedback.
