Tried numerous things to bring back online. Nothing worked so I deleted the icon from my wifi network and went to reinstall drivers but getting error messages that it can't install and to contact developer. &nbsp;This orinter has been great but I'm afraid I may be out of luck. &nbsp;The website says it doesn't support this OS. &nbsp;Any help is appreciated.</P> Wed, 02 Jun 2021 13:50:52 GMT gail14519 2021-06-02T13:50:52Z https://community.usa.canon.com/t5/Desktop-Inkjet-Printers/Can-no-longer-get-mp640-drivers-to-install-on-mac-os-11/m-p/343992#M10397 <P>I am running mac os 11.3.1. &nbsp;Had been printing ok, then printer went offline.
