HP L5 manual Font Type, First Code, Last Code, Bitmap Resolution Data Segment

The remaining fields should be set the same as in the Format 0 Font Header for PCL Bitmapped Fonts, with the following exceptions:

Font Type

Font type describes the font’s relation to symbol sets. For Format 16 bitmap fonts, set this field to 3. A value of 3 is used to identify a large (16-bit) font. All character codes 0 to 65534 are printable, except 0, 7 to 15, and 27 [decimal]. Access to those codes which are unprintable, yet have a character defined, requires the use of the Transparent Print Data command. In older font header formats, PCL 5 LaserJet printers use this field to determine the first and last codes of the symbol set.

First Code

For Format 16 bitmap fonts, set this field to the first printable character in the font. In older bitmap font formats, PCL 5 LaserJet printers ignore this field.

Last Code

For Format 16 bitmap fonts, set this field to the last printable character in the font. In older bitmap font formats, PCL 5 LaserJet printers ignore this field.

One new data segment is defined for Format 16 bitmap fonts:

Bitmap Resolution Data Segment

The bitmap resolution data segment is used to define the x-resolution and y-resolution for the bitmap. This segment is required for Format 16 bitmap fonts.

The structure for the bitmap segment is shown in Table 2-13.
