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)
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…
