Purpose Selects the character spacing for monospaced fonts. This sequence

selects the number of characters printed per horizontal inch on a line.

NOTE: DECSHORP varies the white space between characters, not the

actual character size.

Discussion Pitch Select Mode (DECPSM) activates the Set Horizontal Pitch

(DECSHORP) sequence. When DECPSM is set (enabled), the printer

uses the horizontal pitch of the current font. When DECPSM is reset

(disabled), the printer uses the horizontal pitch selected by the last

DECSHORP sequence.

In addition to changing the amount of white space around characters, this

sequence enacts the following:

• Resets the left and right margins to the printable limits.

• Resets the line home and line end positions to the printable limits.

(Refer to the Page Format Select [PFS] sequence on page 7–64.)

• The current horizontal tabs remain as set.

• Can force the printer into plot mode.

Ps selects the horizontal pitch (characters per inch).
