Windows 10: MS Print to PDF stopped working

I have two Lenovo laptops different models, not networked, both running Windows 64 Professional. All software is up to date.About two weeks ago they both lost the ability to print to pdf. I've tried every suggestion I've been able to find online, without finding a fix, and have run into a problem I haven't seen described anywhere.If I try to add Microsoft Print to Pdf as a printer, when I reach the stage of selecting a port there is no PORTPROMPT or save to file available. The only available port is the one created for my printers. I tried using that, and of course it sent a bad command to t

MS Print to PDF not working

As near as I can tell, this worked BEFORE the latest Windows update.

In Outlook, when I attempt to use the Print to PDF as a print destination, I get an error
"Printer not ready".

Research showed a couple possibilities, so here's what I've done SO FAR:

• Made Print to PDF the default printer (claimed to fix the problem. Didn't work)
• I tried using Outlook in safe mode (Outlook /safe) and received exactly the same error as is "regular" mode.Turned off print to pdf in the windows features and rebooted, then turned back on print to pdf in the windows features. (claimed to fix the problem. Didn't work)
• There are NO commas or any other odd characters in the location to which I'm saving. Tried multiple destinations with no luck. Didn't work.
• Reinstalled Acrobat Reader. Works fine, PDFs open perfectly. Did NOT fix the "Print to PDF".
• When doing a "Print to PDF" from Word, I do not get an ERROR, but no output is created. Same exact thing when trying from a text editor.
• I have deleted and reinstalled the "Microsoft Print to PDF". This CREATES the printer, and allows me to print a test page as part of the installation. I don't get an error, but NO OUTPUT IS GENERATED. Trying to print a test page using print to PDF once the installation is complete (from printer properties, generates an error that says a "parameter is incorrect". No other information is provided.

AGAIN, this has been working absolutely fine since the original installation of Windows 10, using exactly the same versions of Outlook, Word, text editors, etc. As near a I can tell, this has only STOPPED working since the newest "creators update" a week or so ago...

What do now?
