I recently sent our HP1200 for repairs. When it came back it reinstalled it on Jetdirect 500x print server alongwith another 990c. On my 7 user network each time someone sends a print job the printer shows the job status as printed yet at the bottom it shows all listed printed items as queued. As a result, if the server is rebooted the jobs begin to print again. I have no idea how to get around this despite checking server properties, printer propoerties etc. It appears as if the jobs though printed are not flushed from the queue.
