Expand description

ยงSPI - Spacing increment

SPI is used to establish the line spacing and the character spacing for subsequent text. The established line spacing remains in effect until the next occurrence of SPI or of SET LINE SPACING (SLS) or of SELECT LINE SPACING (SVS) in the data stream. The established character spacing remains in effect until the next occurrence of SET CHARACTER SPACING (SCS) or of SELECT CHARACTER SPACING (SHS) in the data stream.

The unit in which the parameter values are expressed is that established by the parameter value of SELECT SIZE UNIT (SSU).
