Brother NC-2010p - Manual (Page 111)

USER’S GUIDE
12-4
e. If you have a bridge or router located between the print server and
host computer, make sure that the device is set up to allow the print
server to send and receive data from the host. For example, a bridge
can be set up to only allow certain types of Ethernet addresses to pass
through (a process known as filtering); therefore, such a bridge must
be configured to allow Brother print server addresses. Likewise, a
router can be set up to pass only certain protocols, so be sure that the
desired protocol can be passed through to the print server.
f. If the job exits the queue but does not print, make sure that you are
not trying to print a text job to a PostScript printer. If you have a
printer that is capable of automatic language switching, make sure
that the printer is not forced into PostScript mode.
Intermittent Problems
If the print server and printer start up OK, but you intermittently have
problems printing, check the following:
1. If you can print small jobs OK but large graphics jobs are distorted or
incomplete, make sure that you have adequate memory in your printer.
2. Check the individual protocol troubleshooting sections in this chapter
for additional causes of intermittent printer problems.
