The Canon Selphy ES1 is the upright sibling in the Selphy lineup—literally. This printer stands on end, a tiny tower of a printer, compared to its prostrate brethren. One major advantage over the other Selphy dye sublimation printers, as well as most other manufacturers’ models, is the lack of an external paper tray. The cartridge and the paper tray are bundled as a single unit and inserted into the printer. This makes the ES1 even more portable than most other dye subs.
