Jet, Ink and Math

I decided to take the go-ahead and buy a printer. Since I don't expect to print a lot, but thought it would be nice if I could print the occasional photo, I bought a cheap inkjet.

Still, I was kinda hungry for the cheap laserjet too. At a price of Euro 99, it would have been a nice deal. The annoying part is the consumables of course, ink cartridges dry out if I don't use them enough, and colour laserjet toners are very expensive at about a Euro 160 per change. Driving home, I puzzled a bit further, and decided that the absurd cheapest deal would have been to buy one cheap inkjet, and about three laserjets - one to print, the rest for cheap toners.

Uh... Bubbles? ... Anyone? ...
