HP PCL/PJL reference (PCL 5 Printer Language) - Technical Reference Manual Part II

EN SI, Absolute Character Size 23-75
Notes If the (SB1;) command is in effect, an SI command may not be
executed accurately. Labels are rendered using the bitmap font that
most closely approximates the character height or width specified by
SI (character size is determined by height for proportional fonts and
by width for fixed-spaced fonts).
When (SB1;) is in effect, characters cannot be mirrored with negative
SI parameters.
Example:Using the SI Command
The following example demonstrates the SI command using both
the default Stick typeface and the Univers typeface. The samples
on the left were printed using the Stick font, first using the default
(11.5-point) and then specifying an absolute character size of 1 cm
wide by 1.5 cm high. On the right, a Univers font was used, first at
12-point and scaled to 1 cm by 1.5 cm using the SI command.

%0B Enter HP-GL/2 mode.
IN; Initialize HP-GL/2 mode.
SP1; Select pen number 1. Even though there is
no physical pen, the SP command must be
used to enable printing.
PA700,3000; Enter absolute plotting mode and move to
(700,3000).
DT#; Define the label terminator as the “#”
character.
LBPrint#; Print the word “Print” in the default font.

Move to (700,2000), specify an absolute
character size of 1cm wide by 1.5 cm high,
and print the word “Print.”
SI; Send SI with no parameters to return to
the default size.
