Horizontal Cursor Positioning (PCL Units)
Command
This Horizontal Cursor Positioning command moves the cursor to a
new position along the horizontal axis.
? * p # X
# = Number of PCL Units
Default = NA
Range = 0 - logical page right bound
A value field (#) with a plus sign (+) indicates the new position is to
the right of and relative to the current cursor position; a minus sign (–)
indicates the new position is to the left of and relative to the current
cursor position. No sign indicates an absolute distance which is
referenced from the left edge of the logical page. The left most
position is 0 and the right most position is the right bound of the
logical page.
If a request is made for a location outside the printer’s logical page,
the current active position (CAP) is moved to the appropriate logical
page limit.
Note The current unit size used in PCL Unit moves is determined by the
value specified in the Unit of Measure command. If no other value is
specified, the number of units-per-inch for PCL Unit moves is one unit
equals 1/300 inch.
