							ENFont Header Format 11-19 Bitmap Font - Specified in PCL coordinate system dots.
Scalable Font - Specified in design units.
Figure 11-3 Character Cell - Bitmap
Orientation (UB)      
Specifies the orientation of the font. All characters within the font must 
have the same orientation as those specified in the font header; 
otherwise they are discarded as they are downloaded.
0 = por trait (0 degrees; the orientation of the raster scan 
of the printer)
1 = landscape (90 degrees counterclockwise)
2 = reverse portrait (180 degrees counterclockwise)
3 = reverse landscape (270 degrees counterclockwise)

Bitmap Font - Unsupported values invalidate font creation.
Scalable Font - set to zero.
NoteHewlett-Packard recommends that bitmap soft fonts be designed in 
portrait (0°), using the paper motion and raster scan direction of 
the HP LaserJet Plus and LaserJet series II printers. The HP LaserJet 
IID, IIP, 2000, and PCL 5 LaserJet printers rotate the fonts to match 
the paper’s physical coordinate system for the various paper sizes.
Spacing (B)   
Specifies the spacing of the font. A value of zero (0) specifies fixed 
spacing and one (1) specifies proportional spacing.
Symbol Set (UI)     
Specifies the symbol set for the font. This value is computed by taking 
the value of the value field for the symbol set, multiplying it by 32, 
adding the decimal (ASCII) value of the termination character (the 
symbol set ID character value) of the escape sequence, and 
subtracting 64.
For example, to compute the value for the ASCII (ISO-6) symbol set 
(Value = 
0, ID = U):
0U = (0×32) + (85–64) = 21
The legal range of symbol set escape sequence field values is 0 to 
2047. Refer to Appendix C in the PCL 5 Comparison Guide for the 
HP defined symbol set values for use in the font header.
HP reserves the right to define the symbol set escape sequence 
value field values of 0 to 1023. Symbol set escape sequence value 
field values 1024 to 2047 are available for use by independent font 
vendors. 
						

							ENFont Header Format 11-21 Symbol set escape sequence termination characters can be any 
upper case ASCII character “A” through “Z.” “Q” is reserved for use 
with HP “Specials” symbol sets and is not recommended for general 
use.
NotesSymbol set ID’s of “@” and “X” do not have a corresponding Symbol 
Set selection command, sets marked as such can be selected only 
with the Font ID.
This field must have a value of 56 for a type 10 or 11 font (unbound 
Intellifont scalable) to be valid. 
Pitch (UI)    
Bitmap Font - Specifies the pitch of the font in quarter dots 
(four quarter-dot units, also known as radix dots, equal one dot). 
It combines with Pitch Extended to specify the pitch of the font in 
1024
th-dots. Pitch defines the default HMI for the font.
For example, a a 17 cpi font designed at 300 dpi has a pitch value of 
70 radix dots as calculated: 
 
The remainder 0.588 is converted back to dots and then to 
1024
th-dots as shown below: 
 
Pitch Extended is set to 150 1024
ths-units. 
NoteFor a proportional font, the width “printed” for a control code Space is 
determined by the pitch value, unless an HMI command is received 
following the selection of the font.
Scalable Fonts - Contains the master design space width 
(escapement) of the font in design units.  
						

							11-22   Soft Font CreationEN
Height (UI) 
Bitmap Font - Specifies the design height of the font in quarter-dots 
(radix dots). This value, converted to points, is used as the height 
characteristic value of the font. A PCL point is   (0.01389) inch. 
It combines with Height Extended to specify the design height of 
the font in 1024
th-dot (fonts designed at 300 dpi).
For example, a 10 point font at 300 dpi has a height of 166 
quarter-dots (radix dots) (1200 quarter dots/inch,   inch/point) 
as calculated:
The remainder 0.667 is converted back to dots and then to 
1024
th-dot for a value of 170 1024th-dot for the Height Extended field 
(similar to that shown in the example for Pitch, above).
Intellifont Scalable - Specifies the master design height of the font in 
 points. A typical value for this field is 2000.
TrueType Scalable - Set the Height field to zero.
xHeight (UI)   
Bitmap Font - Specifies the height of the lower case “x” in 
quarter-dots (radix dots).
Scalable Fonts - Specifies the distance from the baseline to the 
lower case “x” height in design units.

Width Type (SB)   
Specifies the proportionate width of characters in the font. 
Style LSB (UB)    
The least significant byte (LSB) of the Style word. Refer to Style MSB 
for a description of the Style word.
Stroke Weight (SB)   
Specifies the thickness of the strokes used in designing the font. The 
supported stroke weight values are -7 through 7. The thinnest stroke 
available is -7; the thickest stroke weight is 7. The standard stroke 
weight for a medium font is 0; the standard stroke weight for a bold 
font is 3; and, the standard stroke weight for a light font is -3. Table 11-13 Width Type Values

Typeface (UB)           
This field specifies the HP typeface number of the font. The current 
version of this field, supported by the &payette; printer, is described 
first. Then a previous field, supported in earlier printers, is described.
Current Usage 
In the LaserJet 4 printer version of this field, an unsigned short 
integer is assembled from the two unsigned bytes of data. Printers, 
when seeking to match a typeface request with available font 
resources, may treat the typeface number as a single value. If an 
exact match cannot be made, the request may be ignored (for 
selection purposes, however, the font select table is updated).
The procedure for allocating typeface numbers for the font products 
of various vendors, however, will consider the typeface number to be 
composed of two distinct fields: a vendor field (consisting of the four 
most significant bits) and a typeface family field (consisting of the 12 
least significant bits). The following diagram illustrates this scheme:-3 Light
-2 Demi Light
-1 Semi Light
0 Medium, Book, or Text
1 Semi Bold
2 Demi Bold
3 Bold
4 Extra Bold
5 Black
6 Extra Black

							ENFont Header Format 11-25 Vendor Number - Bits 15 - 12. This value is assigned by HP and is 
between decimal values 0 and 15.
Typeface Family Number - Bits 11 - 0 This value is between 0 and 
4095. See Appendix C in the PCL 5 Comparison Guide.
Typeface Family Values are calculated according to the following 
formula:
Example 
The HP typeface number for Agfa Dom Casual typeface is 4157 
(vendor value=1, and typeface value=61): 
61 + (1 × 4096) = 4157 Table 11-15 Typeface Family Value (Current)

Previous Usage   
The previous treatment of the Typeface field supported the LaserJet 
IIP, IID and LaserJet III family printers. It consisted of the Typeface 
Least Significant Byte (LSB; the original, one-byte typeface value 
used prior to the LaserJet IID printer) and the Typeface Most 
Significant Byte (MSB) in the font header.
The previous typeface family value field is shown below. It included 
a 4-bit field to specify the vendor number, a 2-bit field for the version 
number, and a 9-bit field which contained the typeface base number. 
The most significant bit of the MSB was always zero.
Vendor-Version The Vendor-version (bits 10 and 9) value was from 0 
to 3. It changed when the vendor changed the width or design of the 
characters in a font. Table 11-17 Typeface Family Value (Previous)

							ENFont Header Format 11-27 Typeface Base ValueThe Typeface Base Number (bits 0 through 8) 
ranged from 0 to 511. Some of these values referred to the styles 
that vary by structure and appearance width (such as Helvetica 
Condensed, Helvetica Outline, etc.). Do not use these values in 
new designs since they are being deleted. Refer to Appendix C in 
thePCL 5 Comparison Guide for a list of typeface families and their 
typeface base values.
NoteFor future compatibility, use the two-byte (typeface MSB/LSB) 
typeface family value. All scalable fonts use the larger typeface 
family value. Older bitmap fonts use the smaller typeface base value.
Serif Style (UB)   
Specifies one of the following defined serif styles.
Serif Style values 0-63 (the lower six bits of the style field) are ignored 
by the printer for bitmap fonts. However, the upper two bits (bits 6 and 
7) are used by a scalable font header to determine the serif style of 
the typeface insensitive characters to complement the font. Serif style 
values for the lower six bits are listed in the table below. Serif style 
values for the upper two bits are listed in the following table.
