HP toner cartridge

You recently bought a toner cartridge but still, your printer keeps flashing the message, "replace toner cartridge"? Or does your documents come out without any ink or half prints?

You might be thinking what's so big deal about buying a printer and its life supports? What's wrong in picking up any random printer, ink and toners?

When we talk about printers the only brand first comes to our mind is HP. And it is indeed the most popular and reliable brand everybody trusts.
