i keep getting messages that the cartridges need to be authenticated. Very annoying. Don't know how to turn them off. Tech support is non-existent. Paid too much for this printer, otherwise I would the it out the window.
The last time I needed new toner I ordered high capacity cartridges. This is an excellent offer for all laser printer users. These cartridges never dry up and clog like ink jet cartridges do. High capacity cartridges cost less per page to print so it is a bargain.
I bought this a few months ago and it uses a lot of ink, but I am very happy with output quality. I do wish it were possible to scan both sides of a document using this printer and the HP smart app.
