Vertical substitution characters are those characters which change their appearance, orientation, or positioning when written vertically. Examples in Japanese fonts include parentheses, brackets, punctuation and small kana. In the example above, the two small characters are replaced with vertical substitutes. Vertical substitution characters are accessed through the Vertical Substitutes Character Segment, which is described in more detail later in this chapter. Font Header Format 16 The HP LaserJet 4PJ printer provides support for large fonts. Large fonts, such as the MS Mincho and MS Gothic fonts supplied in the printer, are fonts which are bound to large symbol sets. The LaserJet 4PJ printer supports a new font header to accommodate large bound fonts. New segments are provided for support of vertical substitutes, galley characters, typeface strings, and character enhancements. The Font Header Command, described beginning on page 11-6 of the PCL 5 Printer Language Technical Reference Manual, has several different header formats. The support of large fonts adds Font Header Format 16 (Universal Font Header). Font Header Format 16 is identical in structure to format 15 (Universal Scalable Font Header) except that the size field for data segments has been enlarged from 16 bits to 32 bits, and a new Font Type has been added for large fonts (Font Type 3). 2-34 Printer-Specific Differences ENWW
