Spooler Sub system App issue

This was a weird one - on an WinXP system with an HP Laserjet USB printer, an error message started to pop-up constantly, with the following message:

Spooler Sub System App has encountered a problem and needs to close
Error signature
SZ AppName:Spoolsv.exe
SZ AppVer:5.1.2600.2696
SZ Mod Name: SD1MF32.DLL
SZ Mod Ver: 5.60.2209.0
offset:00004537

Quite annoyning - So, I went searching for a fix. Found one!

[Solution]

You need to remove all printers on your system. Un-install the printers on your system, then to clean any left overs.

Remove all files in the directory:

C:\WINDOWS\system32\spool\PRINTERS

Run regedit and remove all entries under this tree:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Print\Printers
Then, you simply re-install your printer drivers and all issues should be resolved.
