Had a client with a printer issue.

This link helped me solve it.

Splwow64.exe error (The program cant start because dll is missing from your computer)

reg_keys_printer

I deleted the folders that are highlighted in yellow. Then I followed the rest of the instructions.

When I came to deleting all the files in the drivers directory I made a back up of all the files first just in case I needed to put them back. I didn’t.

I hope this helps someone else out there…
