My PIXMA MG3520 will not print.


My PIXMA MG3520 will not print when I hit "print"  I get an error message "another computer is using this printer"

Then, sometimes, when I turn the computer off and then back on, it will print the last document that I wanted printed.

Hi James, I have a Windows 10 and connect with WiFi.  I've tried turning off and unplugging the printer, but that doesn't work.
