PIXMA TS7720 Nothing happens after clicking on the Print button in the dialog box

[GME58]

Pixma TS7720 won't print from desktop.  Never had problem before.  The desktop says that the computer is on-line and the print dialog box appears.  Also, scanning function works.  I can print docs using laptop, so it doesn't appear to be a printer problem.

Greetings,

What is the IP address of your printer?

What is the IP address of your computer?

Can you ping the printer's IP address from a command prompt.  Does it reply?

If you open a browser and enter the printers IP, then press enter, does it's webserver display?

Next steps can be provided when you reply..

I know from much experience as a retired computer and computer networking tech that the best troubleshooting tool for an issue like this is a printer cable, it helps to narrow down the source. it will tell you right away if your wifi is the source if you can print using a cable and you can always go back to wifi once the problem with it is resolved. If you have to move a device closer to the other one, it is a temporary inconvenience to help solve a very inconvenient problem.

I was able to perform a nozzle check.  Print function from desktop still does not work.  Desktop scan function works, but scanned doc won't print.  Print function from laptop, also WiFi connected, works fine.
