Remember kids, NEVER get an HP printer, it's all just a money making scam to force you to buy color cartridges in order to print in black and white, because THAT makes sense :D

@Clitheroe: Funny thing with printers is that it uses ink for cleaning, which is why it's needed. Regardless, if you keep empty cartridge in place, it should work just fine at least for while. Unless HP became even bigger dicks lately.
