A family of Microsoft word processing software products for creating web, email, and print documents.
Same just started happening with me last week (Office 365). Tried all suggestions here, nothing seems to work.
Thankfully this does not happen when mass mail merging envelopers. Only one-offs from a letter so I just keep my drawer 1 open and cancel the print job after each envelope prints as so no blank page comes out.
It does not appear to be a separator page as this is off on printer as is print blank pages, but just to test it, I changed my separator page to my 2nd drawer on my printer yet it still prints the blank page from drawer 1. Very frustrating, Please fix this!
