Spoke wit Canon tech support and this worked for me. I have a Maxify MB2720 and the printer port being used was WSD. I disabled WSD and added a static IP address. On your computer, go to control panel, devices and printers, right click on your printer icon, and select properties. In the properties box there should be a tab for "ports". Click ports and if WSD is selected this is what I did. Go to your printer, Lan settings, and disable WSD and determine which IP address is being used, usually 192.168.1.xxx. Go back to your computer, control panel, devices and printers, right click on your printer icon, properties, ports, add port, in the menu choose TCP/IP and next, a dialog box open, select ok, then type in the IP address in the box, both boxes will populate. Select ok, click yes if prompted. Click apply and OK. You will have to do this on each divice connected to your printer. Different operating systems may have different tabs but this is the jist. If you are using windows 10 make sure to go through control panel and not just settings. Hope this helps.
