Spacing Pitch Increment (SPI) (continued)

If a position command does not precede the printable (graphic) character, the

printer will place that character to the right of the previously received

character. The distance between characters depends on the values of Pn1 and

Pn2 in the most recent SPI, SHS, or DECSHORP sequence. If you set the

Pn1 or Pn2 values to 0, or if you do not send an SPI sequence, the printer

uses the default horizontal and vertical spacing for the font currently in use.

Horizontal spacing is the same for all font styles.
