I have an iMac, on Catalina OS, have latest Canon Pixma Pro 100s software for this. I have chased this around for hours and cannot get wifi on it. My trials have me running in circles and I now have a brand new Canon wireless printer that is only recognised through the WIRE connecting the two. Pointless.
Been on various forums including uTube and they all revert me back to "apple/system preferences/Bla, Bla, Bla" None of this identifies the wifi version. Removed the WIRED printer, reloaded frequent drivers and checked it was still up to date.
How do I get round this before returning it to Amazon.
