Hot Print  was designed to continually monitor a 'hot folder' and print a photo of the images that appear in that folder. The hot folder can be any folder selected (including the tethered folder for your camera).  If tethered, as an image appears in the folder, a photo in printed and the original  image copied to a backup folder to preserve it. Current options for photos are 5x7, 4x6 and 8x10.
Warning: all image files in the hotfolder are deleted after processing.
