I am unable to print from a client PC to a printer on a print server using my Linux Ubuntu 7.10 desktop. This problem can occur if you have a firewall installed on the print
server. If you have a firewall running, you need to open port 515 (line
print spooler).
The procedure to configure the firewall can differ
between distributions. For further information, consult the
documentation that came with your distribution.
