ESC D

Function:

Set horizontal tab positions

Code ASCII: ESC D n1 ... nk NUL

Code HEX: 0x1B 0x44 n1 ... nk NUL

Range:

1 ≤ n ≤ 255

0 ≤ k ≤ 32

Default: n = 8, 16, 24, 32, ... (Every eight characters for the default font set by ESC !

or ESC M)

Description:

Sets a horizontal tab to n columns from the beginning of the line.

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

Notes:

• The horizontal tab position is stored as a value of [character width × n]

measured from the beginning of the line. Double-width characters are

selected with twice the width of normal characters. The character width

should be set before using this command.

• 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.

• 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.
