Toshiba Satellite L75D-A laptop.
Recently updated to Windows 10.
HP Photosmart 7520 printer connected through home wi-fi.
Printing from other wi-fi devices (iPad) successful.
Printing from the laptop was successful until two days ago, but now I'm getting a "Paper out" message when I try to print (Word or Excel).
There is paper in the printer and the printer will print - Network Configuration Page printed cleanly from the printer.
Wireless Network Test Results page and Printer Status Report page both printed cleanly from the laptop.
I have confirmed there is paper in the printer, no jams, paper size indications correctly matching, driver is most recent version (not recently updated but confirmed), etc.
No viruses or malware detected.
What am I missing and what do I do next?
Thank you in advance.
