Receipt Paper Printing method: Thermal line printing Dot density: 180 dpi Ч 180 dpi [the number of dots per 25.4 mm (1”)] Printing direction: Unidirectional with friction feed Printing width: 72 mm (2.83”), 512 dot positions Characters per line: 42 (Font A) (default) 56 (Font B) Character spacing: 0.28 mm (.01”) (2 dots) (Font A)(default) 0.28 mm (.01”) (2 dots) (Font B) Programmable by control command. Printing speed - High: Approximately 16.5 lines/second (4.23 mm (1/6”) feed, at 24V, 20° C, density level 2) Approximately 70 mm/second (approximately 2.76”/second) Printing speed - Low:
Approximately 11.8 lines/second (4.23 mm (1/6”) feed) Approximately 50 mm/second (approximately 2.0”/second) High and low speeds are switched automatically depending on the voltage applied to the printer and the temperature of the environment. Approximately 35 mm/second (approximately 1.4”/second) when a ladder bar code is printed. Note: Printing speed may be slower, depending on the data transmission speed and the combination of control commands. 4-2 Reference Information
