Reduced Character Spacing (SRCS) CSI ... SP f
Data Structure ASCII CSI n SP "f" [B] set reduced character spacing
hex. 9B n 20 66
dec. 155 n 32 102
Description n specifies the reduced character spacing
The units are either decipoints or defined by SSU (Select Size Unit, see page 8).
This function reduces the inter character spacing. The function will typically be used with
proportional spacing to get special effects like e.g. kerning.
With fixed spacing, functions like SCS (Set Character pacing, see page 19) should be
used.
The character size will not be changed.
