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 inch

300 dots

= 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.

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.
