Error code: 20 printer not activated on windows 10
A couple days ago, Microsoft updated by Windows 10 software on my laptop. Subsequently, I have lost the ability to save a PDF file from my QuickBooks software. When I attempt to save an invoice as a PDF, I now get this error message: Printer Not Activated, Error Code-20.
Please note that prior to my Windows software update, I had no problems savings QuickBooks invoices in a PDF format. I would appreciate anyone's guidance on how to resolve this problem.
