@Wouter @drwho @malwaretech That's why I will never buy another cartridge printer. The one I've got now is used only with black and white 3ed party ink, and never sees a network connection so cannot downgrade itself to lock that out. Feed rollers barely work, this has been so for years. When it dies entirely, I will buy a tank printer or nothing. Tank printers sell for a bit under $200, as the makers understand there are only two types of inkjet ink and each will work in any other printer that uses the same type (I believe thermal vs magnetic?). That means they cannot sell the printer at cost and then make a killing selling ink in tiny cartridges at a price exceeding what hospitals charge for human blood.
