Appendix A Product Specifications Printing Specifications Roll Paper Printing dpi: dots per 25.4 mm (dots per inch) ∗1: Command configurable ∗2: The above print speed values are based on the following: 24 V, 25°C, standard density level. Printing speed is switched automatically in accordance with the voltage applied to the product and head temperature conditions. The maximum printing speed values above may not be attainable due to command combinations. If the data transfer speed is lower than the maximum printing speed, the printing speed changes, which can cause uneven print density and non-uniform feed pitch.
A slow data transfer speed can also result in intermittent printing, white banding in graphics or other problems. 95 Printing method Line thermal Dot density 180×180 dpi Printing direction Unidirectional with friction feed Print width 72 mm, 512 dot positions Characters per Font A line*1 Font B 42 56 Character spacing*1 Font A Font B 0.28 mm (2 dots) 0.28 mm (2 dots) Line spacing*1 4.23 mm Maximum printin g speed*2 Text printing (with embedded fonts) 300 mm/s (when line spacing is 4.23 mm: approximately 70.9 lps) Page mode printing 300 mm/s Graphics printing in monochrome 300 mm/s Ladder bar code, two-dimensional symbol printing 124 mm/s Graphics multiple tone printing NV/download graphics:
