Spacing Between Characters; The Character Plot Instruction, Cp - HP 7470A Interfacing And Programming Manual

Specifying both parameters as zero will set error 3, and having only
one or more than two parameters will set error 2. The plotter will ignore
such instructions.
Spacing Between Characters
Character spacing and line spacing are functions of character size. In
the diagram below, you can see the relative position of a character, in
this case M, within the character space. The character-space field is set
indirectly by the SI command, since the character space height is twice
the character's height and the character-space width is 11/2 times the
character's width. The space above and beside a drawn character be­
comes the spacing between lines and characters. The character space is
illustrated below.

When you specify the height of a character in an S1 or SR command,
however, you should specify the character height, not the height of a
character space.
The Character Plot Instruction, CP
DESCRIPTIONThe character plot instruction, CP, moves the pen the
specified number of character-space fields.
USES The instruction can be used to move the pen any number of
character spaces or lines from a point on the plotting surface, to align
with a left—handmargin, or to center or right—justifya label. Thus, the
