I have a Canon printer. (Serves me right, you say? How can I argue with that?)
It is an inkjet, utilizing four ink tanks. Whenever one colour runs out the printer driver refuses to operate, even if we are only printing black. And 99% of the time we are only printing black.
Big deal, I can hear you say, so the colour tanks will last forever if you're only printing black. Ah, but the damn ink evaporates. We are constantly replacing colour tanks, just so we can print black. Why do I get this strange feeling I am being screwed? And if I'm being screwed, how come I'm not enjoying it?
