EN Vertical Cursor Positioning (Decipoints) Command 6-11
Vertical Cursor Positioning (Decipoints)
Command
This Vertical Cursor Positioning command moves the cursor to a new
position along the vertical axis.
? & a # V
# = Number of Decipoints (1/720 inch)
Default = NA
Range = –32767 to 32767 (rounded to the first decimal place)
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.
