We are in the course of a migration to Windows 7 Pro 64-bit. Clients print to network printers shared on a Windows Server 2003 R2 SP2 32-bit server. The new clients are experiencing intermittent and sporadic hangs in printing. Restarting the spooler on the client causes all hung jobs to print properly. The local event viewer shows events similar to the following when this occurs:
Event ID 372 in PrintService. Try to print the document again, or restart the print spooler.
Data type: RAW. Size of the spool file in bytes: XXXXXX. Number of bytes printed: 0. Total number of pages in the document: 1. Number of pages printed: 0. Client computer: \\JFWRKXXX. Win32 error code returned by the print processor: 1722. The RPC server is unavailable.
We've completely replaced the drivers for the printers on the server with a new driver model, and reinstalled the printers on clients, but that failed to address the problem. Printers are primarily Ricoh multifunction copiers with a smattering of HP LaserJets.
