Resolving a Persistent spoolsv.exe Error/Crash

Today I was troubleshooting a couple of network printers. One of them, I believed, had an incompatibility with “Standard TCP/IP” printing, via RAW communications. I tired other printer port options, including the HP TCP/IP port. I found out later on that the printer itself (a multifunction copier actually) did not have printing capability enabled. In the process of installing a printer driver later in the day, I ran into this error:

The instruction at “0x00000000” referenced memory at “0x00000000”. The memory could not be “written”.

The error wouldn’t go away. Reboots did nothing. Clearing out all registry references of the printers and drivers that I had been troubleshooting did nothing. Deleting my printer drivers folder only made things worse (as you’ll read later) Even a reverting to an earlier System Restore point failed. Finally, after finding tidbits of information online here and there, nothing with a complete solution, I tried removing this key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Print\Monitors\HP Standard TCP IP port

I then restarted “Print Spooler” in the Services control panel (services.msc), and my Printer control panel finally displayed properly, without crash. Unfortunately for me, I then had to delete all my printers, as I had deleted all of my printer drivers and none of the installed printers were functional.

So if you run into this error, try deleting the key above before attempting anything else.
