here' my problem i have a customer with a small network. They do billing on a
computer that controls 2 printers in parallele mode. Everyone in the business
prints to that computer.
We have a problem with the printers giving error writing to lpt once in a
while but the problem is starting to be more frequent. We reboot that system
and everything is back to normal for a day or more. I'm wondering hwat it
could be.

I tried changing the PCI paralelle card, re installing drivers and also
erasing tmp files. Still the problem persist.
