HP detonates its timebomb: printers stop accepting third party ink en masse

Well, my 15 year old HP still works, but HP no longer makes drivers for it. Plus it uses one of the most expensive liquids in the world, HP printer ink. For the price I just paid for a single ink cartridge I could have bought a new, current printer, or even a printer/ scanner. But it has usb and a parallel port…just in case… Sigh…
