Printer pipes are used to send data from applications to
client print spoolers. The
number of pipes specifies the number of print jobs that can
be sent to the spooler
simultaneously.
The default number of printer pipes is ten.
The Spooler service must be stopped and restarted after
changing the number of
pipes. Print jobs already spooled continue printing.
Print jobs sent to the spooler trigger an error message
while the service is stopped.
Make sure no users start printing during the time the
Spooler service is stopped.
