FI, Select Primary Font
This command allows any accessible font that has been assigned a
font ID number to be selected as the primary (standard) font (the font
characteristics are assigned to the standard font). As mentioned, the
font must be accessible to the printer as either a resident font, a
downloaded font, or a loaded cartridge font. To be selected, the font
must have been previously assigned a font ID number in PCL mode.
Also, for scalable fonts, the FI command must be preceded by an SD
command specifying the font’s point size or pitch (see the “Using the
FI Command” example).
FI font_ ID[;]
When the printer receives this command and the requested font is
present, the primary font characteristics are set to those of the
requested font. If the selected font is proportionally spaced, the
pitch characteristic is not changed.
Notes This command does not select the font for label printing if you are
currently using the alternate font.
The FI and FN commands implicitly change the value of SB. For
example, if SB = 0 and FI selects a bitmap font, SB is set to 1. This
affects the performance of certain HP-GL/2 commands. Refer to SB
command later in this chapter.
Example:Using the FI Command
The following example demonstrates assigning a font ID number from
within PCL mode, entering HP-GL/2 mode, using the FI command to
select that font, and printing a short line of text.
