Can't print wirelessly but printer diagnostic page prints ok
Can't print wirelessly at home from HP Desktop, to HP OfficeJet Pro 6978. Problems started after upgrading to new Verizon FIOS router, with 2G and 5G networks. It took a while to get the printer working, but I got it working. But now after a week or so, it won't print, although today I printed several diagnostic pages from my PC. When printing from Notepad, it just says "Error Printing". Both the PC and the printer are on the same 2G network.
I just noticed that the Diagnostic pages kind of doesn't go through the printer software. I say that because in my printer queue, there's a document with status "Error - Printing", but even with that the Printer Diagnostics page slipped on by and printed without actually going to the printer queue.
But I can print from a MacBook Pro, no issues, even though in my Printer queue there's still a document in error.
