I did solve my issue yesterday - maybe only temporarily. I saw in Print Studio Pro that there are two Printer options - Canon XPS and Canon Printer. I swear that I always had it se to XPS but changed it to Canon Printer and it seemed to solve the problem. I'm not sure why or if it is the real fix - but I'll take it. It is comforting to know that I'm not the only one who has struggled with this.
