In a computer lab configured, run, and used by non-experts we have 8 - 10 standalone FC4 computers all plugged into the Linksys router or its attached Linksys switch. The HP LaserJet 2200 printer has a JetDirect card and is also plugged into the router. Adding the networked JetDirect printer via the desktop's System Settings>Printing menu works just fine and printing proceeds normally from the various applications.
Our most frequent maintenance problem, however, is that eventually (sometimes hours, sometimes weeks) each client fails to have its jobs print. Its print queue will show a backlog of jobs, but they just never print. I have always simply removed the print queue, then re-added it from scratch, then everything is fine until the next time that client loses track of the printer. This happens to all clients with an obtrusive frequency. What can I do to ensure clients' print queues stay healthy for longer periods?
