SimplePrint is a suite of 3 apps that make the painful art of network printing a breeze. Use the Admin tool to set up your printer(s), then you can easily set the default printer, stop and restart print jobs, and view every print queue on your computer -- all with one click. Also included in the suite is the SimplePrint Traffic manager, which will allow you to view all of the printing traffic, move jobs to another print queue, and change priorities of the jobs.
The best thing about SimplePrint ... it's free; at least while in beta. Donations are accepted, however.
