The Planon PrintStik is a battery-operated Bluetooth thermal printer.
Being thermal, the paper's a little more expensive but it never needs ink.
You can pair it with a notebook and print everything.
Right now - and for what I'm guessing will be the next 4-6 weeks - its early-stages BlackBerry drivers will let you print text from e-mail - and optionally kill white space to fit more on a page.
The issue is that HTML details need O/S 4.5 - Planon is a new member of the BlackBerry Alliance and working feverishly on more full-service BlackBerry printer drivers - and until they're out, positioning this as primarily for notebooks - but I've had one for months and it does work.
It's about the size of a roll of wax paper split the long way.
