v Font C is 8 dots (wide) × 16 dots (high) with the last 2-dot row used for
descenders.
(1.0 mm × 2.0 mm character height including descenders, 1.0 mm × 1.75 mm
excluding descenders)
v Font C, starting with level 38 micro code, is 8 dots (wide) and 20 dots (high) with
the last 2-dot row used for descenders.
(1.0 mm × 2.5 mm character height including descenders, 1.0 mm × 2.25 mm
excluding descenders)
The number of characters printed per inch depends on the character size, the
intercharacter spacing, and the chosen font. For example:
v 17 cpi ⇒ 10-dot wide character + 2-dot space (font A) ⇒ 48 characters per line
v 15 cpi ⇒ 10-dot wide character + 3-dot space (font A) ⇒ 44 characters per line
v 12 cpi ⇒ 12-dot wide character + 5-dot space (font B) ⇒ 34 characters per line
v 20 cpi ⇒ 8-dot wide character + 2-dot space (font C) ⇒ 57 characters per line
You can choose the character size of four user-defined character sets (code pages)
or two proportional fonts. The parameter ranges for user-defined character sets are:
v 8 ≤ dot width ≤ 16
v 16 ≤ dot height ≤ 32 (must be a multiple of 2)
The parameter ranges for characters in proportional fonts are:
v 8 ≤ dot width ≤ 32
v 8 ≤ dot height ≤ 32
Notes:
1. Any of the thermal printing fonts can be scaled up to eight times the defined
width and eight times the defined height. The scaling factor for the width does
not have to equal the scaling factor for the height. For example, you could
specify twice the width and five times the height.
2. For paper that has a width of 80 mm, the cash receipt print line is 72 mm (2.83
in.) long. There are 576 dots per line and 203 dots per inch.
Impact printing fonts (Models TI1, TI2, TI3, TI4, TI8, TI9, TG3, TG4, TG8,
and TG9)
The resident character set has a font of 7 half-dots (wide) × 9 dots (high). There are
no descenders.
v Font A prints 150 half-dots per inch = resident character size is 1.2 mm×2mm.
v Font B prints 120 half-dots per inch = resident character size is 1.5 mm×2mm.
The number of characters printed per inch depends on the character size, the
intercharacter spacing, and the chosen font. For example:
v 17 cpi ⇒ font A with 7 half-dot-wide character + 2 half-dot space ⇒ 52
characters per line
v 15 cpi ⇒ font A with 7 half-dot-wide character + 3 half-dot space ⇒ 47
characters per line
v 12 cpi ⇒ font B with 7 half-dot-wide character + 3 half-dot space ⇒ 37
characters per line
You can choose the character size of the two user-defined character sets (code
pages) within the following parameters:
v 4 ≤ half-dot width ≤ 16
v 4 ≤ dot height ≤ 16
