problem with printing

[Alex]

We have 3 PCs in small network two machines-Windows XP,
one machine Windows 98.
The printer is installed on one of XP machines. Both XP
machines firewalls(ICF) is configured manually(opened
approopriated ports) to allow printing &sharing.
We have a periodically problems with printing. For
example, when I print docs(from any machines), the printer
does not print it.
The tasks on XP machine(with the printer) are not executed
(just collects tasks)
Printer driver is standard, OK. What is problem?

We have a similar problem. We have a small network, 2
pcs with XP, networked to 2 dot-matrix printers on an A/B
box. This set up has been in operation for years; XP was
installed one year ago. We print records and labels from
OCLC. All of a sudden, in the middle of a run, records
stopped printing. OCLC show print jobs completed; XP
shows the jobs in queue. Any ideas?
