First the printer must be set to page mode, then the following command should be sent.
Example:
MSComm1.Output = Chr$(&H1B) & Chr$(&H57) & Chr$(&H40) & Chr$(&H0) & Chr$(&H40) &
Chr$(&H0) & Chr$(&H40) & Chr$(&H1) & Chr$(&H40) & Chr$(&H1)
Exception:
This command is effective only in Page Mode.
Set Absolute Vertical Print Position in Page Mode
Hexadecimal:
[(nL + nH X 256) x (vertical or horizontal motion unit)] inches.
Sets the absolute vertical print starting position for buffer character data in
Page Mode.
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
direction 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.
Example:
MSComm1.Output = Chr$(&H1D) & Chr$(&H24) & Chr$(nL) & Chr$(nH)
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.
