Snapshot printers are printers that do not need a desktop or laptop connection for it to do its job. You just have to plug them to an electric socket and insert your media (or memory) card or connect your camera to it to print your files.
This type of printers comes with small LCDs where you can view and select the pictures or files that you want to print. They come in small sizes so you can carry them around. Some of the snapshot printer models can also run on battery so you don’t have to worry about electric sockets anymore.
Less-expensive snapshot printer models only have basic editing features like red-eye removal, clip art options, sepia-toning and border features. The more expensive or high-end models offer more extensive features such as adding captions, drawing or editing the image and printing layouts from albums and calendars.
Snapshot printers normally use one of these two technologies: inkjet and dye sublimation. The first technology is the most common: inkjet. The second technology called dye sublimation transfers the ink from a continuous roll to the paper. The dye sublimation technology produces pictures (or printouts) that are almost dry unlike in inkjet printers where you have to wait for the ink to dry. Also, inkjet technology tends to use more ink and require more frequent ink cleaning and printhead aligning.
