Printer Sharing Problem

I have a peer to peer network with Shared printers on workstations. All were printing until about two weeks ago. I saw an earlier post with the same problem. Here is the erro that I receive when trying to print to the printer from a networked system.

“THERE WAS AN ERROR WRITING TO //path/printer (HP LASER JET 4). THERE WAS A PROBLEM PRINTING TO THE PRITER DUE TO AN UNKNOWN SYSTEM ERROR. RESTART WINDOWS, AND THEN TRY PRINTING AGAIN. THIS PRINTER WILL BE SET TO WORK OFFLINE. TO SAVE YOUR PRINTJOB IN THE LOCAL PRINTER QUEUE, CLICK OK.”
