Why is my printer not printing Microsoft Word documents?
If you can’t print a test page, or if you cannot print in several or all Windows-based programs, the problem might be related to a printer driver, hardware, the operating system, or internet connectivity. If the problem is limited to a particular font, a corrupted font file may be the cause.
Can you set a default printer for Word?
Go to Devices > Printers & scanners > select a printer > Manage. Then select Set as default. If you don’t see the Set as default option, the Let Windows manage my default printer option may be selected. You’ll need to clear that selection before you can choose a default printer on your own.
