New Depths of Printer Evil
I frequently say, only half-jokingly, that printers are evil. Actually I love my HP LaserJet 1320, but my Canon Pixma 620 is just plain E-V-I-L.
OK, pretty much any inkjet printer is devil-spawn, with the well-cited fact that printer ink is the most expensive liquid on the planet. Canon has taken the Pixma to a new level, though, because while it is a combination printer/scanner/fax, you can't do anything useful if you're out of ink. Notably, in spite of the fact that no bits need converting to atoms when scanning an image to your PC, you just can't do it if you're out of ink. All you get is a message on the display stating, "The following ink has run out. Replace the ink tank."
Yeah, the printer/scanner is pretty good when you're willing to open a vein to fill the ink, but disabling non-ink functions by fiat is just infuriating.
