Mike - thanks for the clue on Windows resetting the default driver.
Along the same lines, about 3 or 4 months ago, I had a windows update that took out all my drivers and I have 39 printer drivers currently.
A month later, also like you, no printer found..... did the Chaney fix.
Next update reduced ALL the text to 10 point size and icons to beads.... and removed the TEXT SIZE adjuster which has been in Windows forever.
Text of 10 points in many applications, is far too small for my eyes.
So I uninstalled that update, and shut off Windows UPDATES so it will not auto update, and no more problems.
Mike promised to let me know if and when they replace that fonts size adjuster.
(I did manage to find a stand alone font size program, in case)
Too old to go through W 10 nonsensical update once a week and then spend two days trying to fix what they broke.
