It seems with every update I get for Windows 10, it changes my printer setting and the printer doesn't work. I made a simple "flow chart" to make changing it back quick and not so aggravating.
Control panel >>> Hardware and Sound >>> Device and printers >>>
HP Photosmart (the name of the printer I use) >>> see what's printing >>>
select your printer again >>> Printer >>>
make sure "Use as default printer" is checked, "Use printer offline" is unchecked
I hope it works for you.
