ENWW Printer-Specific Differences 2-65
The Segment Size field, which is part of each segment within the
Segmented Font Data, was changed from an unsigned integer in
Format 15 to an unsigned long integer in Format 16. This allows
segments to be up to 2
32
– 1 bytes long.
Font Header Format 15 is described in more detail in the PCL 5
Printer Language Technical Reference Manual in the “Soft Font
Creation” chapter.
Format 16 supports new segments and new values for the Font Type
and Font Scaling Technology fields. New segments which are specific
to large TrueType fonts are described in this chapter in the section
titled “HP LaserJet 4PJ printer.” (This information will included be in
future versions of the PCL 5 Printer Language Technical Reference
Manual.) The new segments and values which are specific to bitmap
fonts are described below.
