In companies where sizeable networks support considerable numbers of printers, it would
be useful to have a mechanism to notify the Network Administrator if any problems arise
with any of the printers. To this end, Callisto has a facility to send an e-mail to the
Network Administrator should a print job be redirected due to a printer failure or error.

Since an e-mail message is generated only when a print job is redirected due to a printer
error, it is necessary to enable the status checking for the output queues. If status checking
is not enabled, there is no way to determine if a printer is in error.

If this facility is required, the Callisto Service Configuration dialog has the necessary
option and edit boxes to enter the e-mail addresses. This dialog can be found under
Service|Configure Service.
