I have Microsoft 8.1 and an HP Office Jet Pro 8600 Plus. I type letters with Word and Initially could print envelopes using the "mailings" feature. After a few weeks, envelopes would only print intermittently. Now envelopes won't print at all.
I've tried many suggestions from people on various sites. I ran a piece of plain paper through to see if I had the envelope in the wrong place. No print anyplace on the paper. We re-installed the printer drivers, and that didn't help.
This is not a problem of the printer not getting the message to print; it picks it up and runs it through, but out comes an envelope or a paper with no print, even though the preview pane shows that there will be an address and a return address.
