Description:
In page mode, moves the vertical printing position to (n

+ n
H
× 256) ×
(vertical or horizontal motion unit) from the current position.
Notes:
• This command is enabled only in page mode. If this command is
processed in standard mode, it is ignored.
• The printer ignores any setting that exceeds the printing area set
by ESC W.
• A positive number specifies movement to the downward, and a negative
number specifies movement to the upward. N pitch movement to the
downward: (n
L
+ n
H
× 256) = N. Use the complement of N for setting N
pitch movement to the upward: (n
L
+ n
H
× 256) = 65536 – N.
• The horizontal or vertical motion unit is used for the print direction set
by ESC T.
• When the starting position is set to the upper left or lower right of the
printing area using ESC T, the vertical motion unit is used.
• When the starting position is set to the upper right or lower left of the
printing area using ESC T, the horizontal motion unit is used.
• Even if vertical or horizontal motion unit is changed after changing the
printing position, the setting of printing position will not be changed.
• The vertical or horizontal motion unit is specified by GS P.
