CHAPTER 2 PCL - 70
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 the HL Series printers. This word specifies the height (for Bitmap fonts) or the
distance from the baseline (for Scalable fonts) of a lower case 'x' in 1/4 dots.
Width type (SB) - ignored by the HL Series printers. This byte specifies the font character width according
to the table below.

Style LSB (UB) - see Style MSB.
Stroke weight (SB) - valid values are from –7 to +7. 0 denotes the normal (Roman) stroke width, –7 is the
lightest possible stroke and 7 is the boldest.

Typeface family (UB) – the typeface. This word is made up of the Typeface MSB and the Typeface LSB and
identifies the typeface by number.
Bits 0 to 11 specify the typeface family and bits 12 to 15 specify the vending company.
