Citizen PD22 Portable Printer (1000751)
2" / 48mm print width. Lightweight: <250g. AA batteries
The easy-to-use drop-in-paper-loading system means there is no fiddling with loading rolls of media. Drop the media in to the paper holder and close the lid on the leading edge of the paper and its done!
The printer uses standard AA-size batteries meaning that you can use standard 'alkaline' batteries or recharable NiMH (or any other AA-size batteries). This means, in case of 'emergency' you can always buy a set of batteries from any store if you unexpectedly run out whilst out-and-about.

The PD22 includes IrDA (infra-red) and RS232C serial interfaces as standard.

 
Standard kit includes printer, sample roll and set of AA alkaline batteries.   Use NiMH rechargables from local shops
