HP PCL/PJL reference (PCL 5 Printer Language) - Technical Reference Manual Part I

6-12 Cursor Positioning EN
Vertical Cursor Positioning (PCL Units) Command
This Vertical Cursor Positioning command moves the cursor to a new
position along the vertical axis.
? * p # Y
# = Number of PCL Units
Default = NA
Range = –32767 to 32767
A value field (#) with a plus sign (+) indicates the new position is
downward from and relative to the current cursor position; a minus
sign (–) indicates the new position is upward from and relative to the
current cursor position. No sign indicates an absolute distance from
the top margin. The top position, defined by the top margin, is 0 and
the bottom position is determined by the bottom of the logical page.
Note Since the top margin can be changed using a printer command, the
physical location of the point (0,0) may change. This affects the cursor
position on the 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.
