Small Printers - any good ones out there???

[speed8]

As per the title. I need a small printer to travel with me. Needs to be light, do A4 prints, colour, decent resolution and photo quality would be nice but not necessary. Bluetooth would be fantastic and rechargeable batteries would be great too. I'd like it to be able to handle temperature extremes (0-50degC) and sandy/dusty environments but I can get by without that if need be (and just reduce the lifetime of it instead).

I know I'm not asking for much but the last time I bought a printer and Epson 300 was considered state of the art

Any ideas or recommendations

Cheers
