PRESCRIBE Command Reference
154
Function
The LDFN S command allows outline fonts (TrueType fonts) to be downloaded to the
printing system. A binary format is used to represent font data. The size of this data must
match that given by length (font data length).
Always explicitly terminate font data using WRED;. The five bytes represented by
WRED; are not counted as part of the font data length.
The maximum number of fonts that can be downloaded is up to the memory available or
256 fonts (512 when format is 2). Use FONT or SFNT command to select 1-byte fonts to
be defined with this command.
TrueType fonts defined using this command cannot be completely deleted unless both
DELF n; and DELF n+1; are specified.
A command error will result and the command has no effect if any of the parameters are
outside the given range. This command is ignored if even one parameter error occurs.
Although symbol-set, style, stroke and type-face may be omitted, we recommend that all
parameters be used to define font selection information.
