[HH] mini printers

[Tom Metro]

Apparently there is a trend of hooking up cash register style small
thermal printers to computers or directly to the net to print tweets or
whatnot. Early versions were hacked together (probably from surplus
components), then adafruit made a kit, and now there are a few
commercial products (see video embedded in article).

A Wired article covering the field:

A creative way to waste paper, or useful?
