The Typeface family number can be 0 to 4095.  This value is calculated as follows; 

(TrueType base value) + (Vendor value 

x

 4096) = Typeface Family 



Serif style (UB) -  
Bitmap font - ignored by these printers. 
 Scalable font - values for the lower 6 bits are ignored and values for the upper 2 bits indicates the serif style.  
Bit 6 indicates sans serif and bit 7 indicates serif.  



Quality (UB) - ignored by these HL Series printers. This byte specifies the fonts quality according to the 
following table. 



Placement (SB) - ignored by these HL Series printers. This byte specifies the placement of characters 
relative to the baseline according to the following table.   



Underline distance (SB) -  
 Bitmap fonts - the distance in dots from the baseline to the underline.  A positive value places the underline 
above the baseline,  a negative value places it below the baseline.  A value of 0 places it on the baseline. 
Scalable fonts  - ignored by these printers.  This value should be set to 0. 



Underline height (UB) - the height of underline itself. 
Bitmap fonts - this value is fixed at 3 dots. 
Scalable fonts - ignored by these printers.  This value should be set to 0. 



Text height (UI) - ignored by these HL Series printers.  
 This word specifies the spacing between successive lines of text in 1/4 dots for bitmap fonts and in design 
units for scalable fonts.  This is normally about 1.2 times the fonts height. 



Text width (UI) - ignored by these HL Series printers.  
 This word specifies the average width of the fonts lowercase characters in 1/4 dots for bitmap fonts and in 
design units for scalable fonts. 



First code (UI) - ignored by these printers.  This word specifies the character code of the first (lowest 
numbered) printable character in the font. 



Last code (UI) - specifies the character code of the last (highest numbered) character in the font.  If this 
value is less than 255,  it is recognized as 00FFH. 



Pitch extended (UB) - the fractional part of the character pitch. For a 17 cpi font the bytes value would be 
calculated as follows:  
  

- 

1200/17  = 70.588  

The Pitch byte takes the value 70. 

- 

Pitch Extended = 0.588 

x

  256 = 150 (rounded down).   

( According to HP's manual,  this should be set to 0.)  This printer ignores the value for scalable fonts. 



Height extended (UB) - the fractional part of the height of the font. For a 10 point font the bytes value would 
be calculated as follows: 

1200 

x

 10/72 = 166.667, the Height byte takes the value 166 

Height Extended = 0.667 

x

 256 = 170 (rounded down).    

Point size = (character height 

x

 256 + extended character height) 

x

 300 / (72 

x

 1024)   

( According to HP's manual,  this should be set to 0.) These printers ignore the value for scalable fonts. 



Cap height data (UI) - ignored by these HL Series printers. This word specifies for the font the distance 
between the baseline and the top of an unaccented capital letter (for example, 'H'), as a percentage of the 
font's em rule, '—'.
