Set Absolute Vertical Print Position in Page Mode

ASCII	GS $ nL nH
Hexadecimal	1D 24 nL nH
Decimal	29 36 nL nH

Sets the absolute vertical print starting position for buffer character data in Page Mode. The absolute print position is set to [(nL + nH X 256) x (vertical or horizontal motion unit)] inches.

The vertical or horizontal motion unit for the paper roll is used and the horizontal starting buffer position does not move.

The reference starting position is set by Select Print Direction in Page Mode (1B 54). This sets the absolute position in the vertical direction when the starting position is set to the upper left or lower right; and sets the absolute position in the horizontal when the starting position is set to the upper right or lower left. The horizontal and vertical motion unit are specified by the Set Horizontal and Vertical Minimum Motion Units (1D 50) command.

The Set Horizontal and Vertical Minimum Motion Units (1D 50) command can be used to change the horizontal and vertical motion unit. However, the value cannot be less than the minimum horizontal movement amount, and it must be in even units of the minimum horizontal movement amount.

Formulas

[(nL + nH X 256) x (vertical or horizontal motion unit)] inches.

Exceptions

This command is effective only in Page Mode.

If the [(nL + nH X 256) x (vertical or horizontal motion unit)] exceeds the specified printing area, this command is ignored.
