I am looking for advice regarding a small photo printer that would be used for printing directly from the camera or SD card. I usually provide photographer services for the small school where I teach. Currently, I hand the card off to whoever has requested the service for them to take and have prints made. I think it would be nice if we would just make them on site during the event. Any ideas? I haven't done any home printing in many years. It would need to be fairly inexpensive and easy to operate. Thanks in advance.
