Mini-Printer or Travel Printer

[Lucavi]

So I'm off for a 3-week TDY come this Friday and will be back on the 15th of June, and am looking for a portable or travel printer for work. I haven't had much luck in finding a good one, so I figured I'd open things up to BG.

In terms of price, its not a complete concern as the company will pay for it, but I'd like to keep things between $20-$50 if possible. I could go higher if needed, though, if it means the difference between a reliable one and a piece of crap.

The only decent travel printer that i know of is the HP Officejet 460 (no longer available) and its follow-up model Officejet 100. Those are small inkjet printers that are made for mobile use, come with USB and bluetooth, and you can attach a battery pack.
Drawback is that they are quite expensive (~230$) and the ink cartridges aren't cheap either.
There might be other/cheaper printers, i just happen to know them because a customer of us ordered a few of them together with special laptop cases that fit the laptop and the printer for their technicians. They are (so far) construction site "approved", out of 5 printers only one made problems (battery pack died) and then broke completely after 1 1/2 years of use in rough surroundings.
