Those are hard to come by.
The two I am aware of are HP Officejet 100 (regular paper) and Brother Pocketjet (thermal). They are not exactly cheap though, and they are not commonly found in typical consumer electonics stores like FS.

I think the HP printer is the better choice. However...
- this is not a wifi printer, but a Bluetooth printer
- this printer does not support AirPrint. So it may not support tablets like the iPad.

If you want battery-operated printers, you'll have to compromise on some features. Printers are not exactly the most energy-efficient devices out there; if you are adding extra features, it may start running out of battery in the middle of printing a page.
