Portable printers are notable for their compact size and battery-powered operation, which means they do not need an electrical outlet to work. You can find A4 inkjet printers suitable for printing photos, but most portable printers are thermal printers designed for printing receipts and labels.
Portable printers include mobile devices for printing on the go and handheld devices for printing self-adhesive labels. Travel printers are suitable for professionals who often work outside the office but still need access to printing equipment. There are also multifunction travel printers that function as scanners and copiers as well as printers.
