I have Canon MG6250 and a ix6550 printers - I moved to Mac OS Catalina a few days after Catalina released. Both printers worked perfectly without any problems until 2 days ago when the ix6550 would not printer and said some problems with filter this morning the MGS 250 stopped working with same message. I have spent virtually hours trying to find a solution with absolutely no success - It looks like Apple have withdrawn support for both these printers and do not now supply drivers for Mac OS Catalina. I spent an hour on the phone this morning with Apple and got nowhere - welcome any comments or advice.
