A thermal printer that needs no ink or toner
A thermal printer prints on heat-sensitive paper, so there are no ink cartridges or toner to replace; the only consumable is a 58 mm paper roll. The device connects to the dock through a 9-pin pogo pin connector: you set it in the dock and the contacts make the connection, with no cable to plug in. The USB-A, RJ12 and RJ45 ports on the dock stay free for peripherals and a network cable.
