A PDF printer is a printer. I have thousands of printers installed on some of my servers. None are real, they just exercise the driver and the print path
If you have Pro or Ultimate launch printmanagement.msc
Anything else open Devices and Printers
Any printers defined? If none verify the Print Spooler service is running.
You could just add a fake printer to LPT1 using one of the Generic print drivers and set it as default. Office will typically read the settings for the default printer in order to configure the page and paper size. If the printer driver causes problems with
the application memory, the application will terminate.
