From Christian Dunn:
Print Queue Manager is a printer queue controller for local or remote printers. Simply choose a computer and the application will find all available print queues. Once found you can pause and delete jobs or you can hold an entire print queue and only pass selected jobs to the printer. This can help make enormous paper savings, ensure company document privacy and stop unwanted print jobs making it to the printer. The new job monitor allows you to see jobs appear in the queue in real time without refreshing the list. Includes a full reporting module. PQM works better on an authenticated domain network where permissions can be applied across the network to allow access to printers.
