• 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),
the value of Pitch (UI) should be 141.
The remainder of 0.17646 is calculated as pitch extended:
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) ÷
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,
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.
• Style LSB (UB) - see Style MSB.
