Chapter 2 Configuring the PCL-II Emulation with Control Codes

Cursor Control

Absolute and relative cursor control are provided for the printer. Cursor moves

are made in the current active pitch and current active vertical spacing. The

following escape sequences perform these functions:

Absolute Row ESC&a#R

Move cursor to absolute row # (where # is an unsigned

integer)

Absolute Column ESC&a#C

Move cursor to absolute column # (where # is an

unsigned integer)

Relative Row ESC&a[+#]R

Move cursor to relative row # from current position

(where # is a signed [+ only] integer)

Relative Column ESC&a[+/-#]C

Move cursor to relative column # from current position

(where # is a signed [+/-] integer)

The vertical cursor positioning commands move the current active position to

the same column on a new line; the vertical movement is based on the active

vertical spacing.

The horizontal cursor positioning commands move the current active position

to a new column on the same line; the horizontal movement is based on the

active horizontal print pitch.

The first column/row within a line/page is column/row zero. Therefore, the

upper left-most position is position (0,0). This escape sequence ignores

margins and can therefore be used to set the current active position to any

location within the printer’s physical limits. If a request is made for a location

outside the printer’s physical limits, the current active position is moved to the

appropriate limit.

Note A plus (+) or minus (-) sign in front of the value indicates that

the new position is relative to the current active position. A

(+) sign means the new position is to the right (horizontal) or

that paper motion is forward (vertical). A (-) sign means that

the new cursor position is to the left of the current active

position. The printer does not perform reverse paper motion.
