(default)
Character size	Standard/Double-height/Double-width/Double-width and Double-height
	Font A: 1.69 × 3.38 mm/1.69 × 6.77 mm/3.38 × 3.38 mm/3.38 × 6.77 mm
	Font B: 1.27 × 2.40 mm/1.27 × 4.79 mm/2.54 × 2.40 mm/2.54 × 4.79 mm
Number of characters	Alphanumeric characters: 95; International characters: 48
	Extended graphics: 128 × 11 pages (including user-defined page)
Printing speed	High-speed mode:
	170 mm/s {6.69"/s} max.; 40.2 lps (4.23 mm {1/6"} feed)
	Ladder bar code and 2D code: 100 mm/s {3.9"/s}
	Low-power consumption mode:
	150 mm/s {5.91"/s} max.; 35.5 lps (4.23 mm feed {1/6"})
	Bit image, Ladder bar code, 2D code and Page mode: 60mm/s {2.4"/s}
	The above speed values are approximate.
	The values are when the printer prints with density "Normal" at 24 V and
	25°C {77°F}
	Speed is adjusted automatically depending on the voltage applied and
	head temperature.
