There's so many.. some just attach to the camera where as others will also take memroy cards and/or bluetooth (print from a phone camera), do you want a tilt up screen and are you happy with cheaper inks which fade after a few years or good inks or even sublimation printers (like some fujis)

Most go for kodak or canons as they were designed to be camera printers where as Epson or HP came from their PC printer technology..

Have a walk round some photo/computer stores as you really do need to see the item, see how it connects to the camera in question and also how easy it is to replace the ink (also costs of the inks)
