Had a users who had their printers disappearing and even after reboot or Print Spooler Service restart the printers would vanish after only a few seconds. After much research found this article from Chicago Tech that explains in detail how to troubleshoot this Faulting Application spoolsv issue. Here are the three steps that fixed the issue for this domain user:

Step 1: Clear the print caches to fix Faulting Application spoolsv

1. Open “Computer” and browse to the folder “c:\windows\system32\spool\printers” and delete all the files in the folder.
2. Do the same to clear the content in the folder “c:\windows\system32\spool\drivers\w32x86”

If the above step doesn’t work, please perform the next one.

Step 2: Reset the printer spooler to fix Faulting Application spoolsv

1. Open command prompt as administrator
2. Type “Net stop RPCSS” (without quotation marks) and press Enter.
3. Type “sc config spooler depend= RPCSS” (without quotation marks and note the spacing) and press Enter.
4. Type “Net start RPCSS” (without quotation marks) and press Enter.
5. Type “Net start SPOOLER” (without quotation marks) and press Enter.
6. Delete the printer and reboot the computer to allow Group Policy to re-install printer.

If the issue persists, please go on to Step 3 since the issue can be caused
by some corrupted printer drivers on the computer.
