Printers are a scam.  For one thing, they're sold at a loss!  This may sound like it makes them the opposite of a scam, but given that the company has to make money somehow.. they scam you on the ink.  In fact, the printer itself will often report your ink low when it isn't. Some even add cyan ink to black to "make it blacker", which 1. isn't how black works and 2. wastes your color ink even when you're trying to save it by printing black and white!  Don't try to refill the cartridge, or mess with the printer, or you'll void your warranty! Most of all, don't think for a second of using a different brand of ink!  A single ink cartridge will set you back twenty dollars or more, where the cost of manufacture might be as high as (drumroll please)...

Seven cents!
