In July 2009 we started experiencing Print Spooler crashes on our W2K3 SP2 print servers.

Check the event log and you'll see something akin to this:

Faulting application spoolsv.exe, version xxxxxx, faulting modeul gdi32.dll, version xxxxxxx, fault address 0x00037453

This seems to have been induced by the July 2009 patch KB961371 - MS09-029.

This patch has been re-released to the public, and I can confirm it does indeed fix the problem. It can be found it here for W2K3 SP2:
