HP PHOTOSMART PRINTER PRO B8350
Rather brassed off as has worked until recently with my iMac running Catalina - printing USB - its an A3 printer which I use for my graphic work - suddenly Malware signs come up all over the place and I cannot print! having over the recent years converted to Apple on all my devices - not happy - please advise -
