Windows 2000 SP4 Printing Problem

I was upgrading my windows 2000 print server which was in SP3 to SP4. After applying the SP4, all of my users can not print to the network printers. In the server system event log, the following was recorded: The document xxx owned by xxx failed to print. Win32 error code returned by the print processor: 3003 (0xbbb). Event ID:61, Source: Print. I have to restored to SP3. Anyone had experienced the same thing can share with me the solution?
