IBM TM7 - Manual (Page 118)

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 80-mm paper, the cash receipt print line is 72 mm (2.83 in.) long. There are
576 dots per line and 203 dots per inch.
3. For 58-mm paper, the cash receipt print line is 50 mm (1.97 in.) long. There are
400 dots per line and 203 dots per inch. (This paper width is supported only on
Models TF7 and TM7. Support is available by an RPQ.)
Impact Printing Fonts (Models TI5 and TG5 Only)
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 × 2 mm.
v Font B prints 120 half-dots per inch = resident character size is 1.5 mm × 2 mm.
For DBCS code page 949:
v A double-byte character is 16 half-dots (wide) × 9 dots (high).
v A single-byte character is 8 half-dots (wide) × 9 dots (high).
For DBCS code page 932, 950, and 1381:
v A double-byte character is 16 full-dots (wide) × 16 dots (high).
v A single-byte character is 16 half-dots (wide) × 16 dots (high).
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
⇒ font A with 7 half-dot-wide character + 2 half-dot space ⇒ 52
characters per line
– 15 cpi
⇒ font A with 7 half-dot-wide character + 3 half-dot space ⇒ 47
characters per line
– 12 cpi ⇒ font B with 7 half-dot-wide character + 3 half-dot space ⇒ 37
characters per line
v For DBCS code page:
– For DBCS code page 949: 16 half-dot-wide character + 6 half-dot space
Font A: 150 half-dots per inch
⇒ 21 characters per line
Font B: 120 half-dots per inch
⇒ 17 characters per line
– For SBCS code page 949: 8 half-dot-wide character + 3 half-dot space
Font A: 150 half-dots per inch ⇒ 43 characters per line
Font B: 120 half-dots per inch
⇒ 34 characters per line
– For DBCS code pages 932, 950, 1381: 16 full-dot-wide character + 6 half-dot
space
Font A: 150 half-dots per inch ⇒ 12 characters per line
Font B: 120 half-dots per inch
⇒ 9 characters per line
