I have a Pixma MG7720 that only lately has not allowed printing from multiple computers unless I stop, then start the print spooler on the computer attempting to print. When this started, I had all the computers connected wirelessly, however, I am now using the USB connection on the desktop close to the printer. Since then, the wireless computers are the issue. I am using the latest drivers for the printer and Windows 10 is updated on all computers.
