My brother is after a little printer to use in his van (via a laptop) when he's on site. Portable printing is not something I know about so I would appreciate any advice you can give. Is it just a case of getting a little 12v inverter thing and buying a suitable printer or is there any specific devices that are designed for this type of thing? If it is just a normal printer I need, can anyone recommend a nice little compact printer, either laser or inkjet, black or colour? Thanks a lot.
