•
Pitch (UI) - This value defines the default spacing for each point size in 1/4 dots. Combined with Pitch
Extended to specify the pitch of the font in 1/1024 dots. This is available for fixed pitch font characters
including the space character, and the space character of proportional spacing fonts.
For example, in case of a 17 cpi font (at 600 dpi),
= 141.17646
1 inch 600 dpi
4
17 chara.
1 inch 1
the value of Pitch (UI) should be 141.
The remainder of 0.17646 is calculated as pitch extended:
0.17646 256
4 1
= 45.17376
the value for pitch extended is 45.
For Intellifont-scalable fonts only, the default HMI is calculated as follows.
Default HMI (in dots) = (300 x master design pitch x required point size) ÷
{Master x Resolution ÷(height x 8)}
Default HMI ( in dots ) =
(300 x master design pitch x required point size) ÷ {72.307 x scale factor}
•
Height (UI) - specifies the height of the font in 1/4 dots. Combined with Height Extended to specify the height
of the font in 1/1024 dots. This value can be converted to the point size (1/72").
For example, in case of a 10 point font at 300 dpi,
10 point
72
1
1 inch
300 dots
1 dots
4
= 166.667
This value is normally set to 2000 for Intellifont and should be set to zero for TrueType fonts.
•
x-height (UI) - ignored by this HL Series printer. This word specifies the height (for Bit mapped fonts) or the
distance from the baseline (for Scalable fonts) of a lower case ‘x’ in 1/4 dots.
•
Width type (SB) - ignored by this HL Series printer. This byte specifies the fonts character width according to
the table below.
Value Width type
–5 Ultra compressed
–4 Extra compressed
–3 Compressed or Extra condensed
–2 Condensed
0 Normal
2 Expanded
3 Extra expanded
