Im experiencing spooler issues with a printer. The print spooler would disable its self randomly after being reinstalled.
First step, I would take to troubleshoot the issue is
Right click Start
Explore / Windows / System32 / Spool and delete all files in the Drivers& Printers folders.
Boot PC into Safe Mode
Start / Run / Regedit
System / CurrentControlSet / Control / Print and Open Environment & Monitors
I would delete all files not folders in Windows NTx86/ Drivers & everything except the five standard files inside the Monitor folder.
After reinstalling spooler Im able to print for a few days until spooler disables its self again.
