Thermal Printing Font
There are three font sizes for the resident character set on Models TI5, TG5, TF7,
and TM7:
v Font A is 10 dots (wide) × 20 dots (high) with the last 2-dot row used for
descenders (1.25-mm × 2.5-mm character height including descenders, 1.25 mm
× 2.25 mm excluding descenders).
v Font B is 12 dots (wide) × 24 dots (high) with the last 2-dot row used for
descenders (1.5-mm × 3.0-mm character height including descenders, 1.5 mm ×
2.75 mm excluding descenders).
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).
There are two character sizes for a DBCS code page:
v A double-byte character is 24 dots (wide) × 24 dots (high) or 3.0-mm × 3.0-mm
character height.
v A single-byte character is 12 dots (wide) × 24 dots (high) or 1.5-mm × 3.0-mm
character height.
The number of characters printed per inch depends on the character size, the
inter-character spacing, and the chosen font. For example:
v For SBCS resident code page:
– 17 cpi ⇒ 10-dot wide character + 2-dot space (font A) ⇒ 48 characters per
line on 80-mm paper or 33 characters per line on 58-mm paper
– 15 cpi ⇒ 10-dot wide character + 3-dot space (font A) ⇒ 44 characters per
line on 80-mm paper or 30 characters per line on 58-mm paper
– 12 cpi ⇒ 12-dot wide character + 5-dot space (font B) ⇒ 34 characters per
line on 80-mm paper or 23 characters per line on 58-mm paper
– 20 cpi ⇒ 8-dot wide character + 2-dot space (font C) ⇒ 57 characters per line
on 80-mm paper or 40 characters per line on 58-mm paper
v For DBCS code page:
– For DBCS characters: 6.7 cpi ⇒ 24-dot-wide character + 6-dot space ⇒ 19
characters per line on 80-mm paper or 13 characters per line on 58-mm paper
– For SBCS characters: 13.5 cpi ⇒ 12-dot wide character + 3-dot space ⇒ 38
characters per line on 80-mm paper or 26 characters per line on58-mm paper
You can choose the character size of three user-defined character sets (code
pages) within the following parameters:
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:
