ESC D

n specifies the number of digits from the setting position to the left edge of the print area.

k indicates the number of horizontal tab positions to be set.

The horizontal tab position is stored as a value of [character width × n] measured from the beginning of the line. The character width includes the right-side character spacing, and double-width characters are selected with twice the width of normal characters.

The character width should be set before using this command. Settings of character fonts, space width, and enlargement affect the setting of character width.

A maximum of 32 horizontal tab positions can be set. Data exceeding 32 horizontal tab positions is processed as normal data.

This command cancels any previous horizontal tab settings.

Transmit [n]k in ascending order and place a NUL code at the end. ESC D NUL cancels all horizontal tab positions.

When [n]k is less than or equal to the preceding value [n]k-1, horizontal tab setting is finished, and the following data is processed as normal data.

k is not transmission data to the printer.

Even if the character width is changed after setting the horizontal tab positions, the setting of the horizontal tab positions will not be changed.

Horizontal tab position settings are effective until ESC @ is executed, the printer is reset, or the power is turned off.

Print position can be changed by HT.

When the left margin setting is changed, the horizontal tab position is also changed.

Horizontal tab positions that exceed the print area can be set. In this case, when the print area width is changed, available horizontal tab positions are changed.
