Sets multiple horizontal tabs. A maximum of 28 tabs may be set with one command. Note that this control command is terminated with a null byte.

This command clears all existing horizontal tabs. Therefore, to add one tab, you must include all existing tabs plus the new one.

ESC D only sets the tabs. The Horizontal Tab control code, HT, causes the printer to tab to each subsequent tab.

n denotes the character position of each tab. The valid range for n is from 1 to one less than the right margin minus the left margin. Send the values of n in ascending order. An out of order tab value is interpreted as a terminator.

The tabs are set relative to the left margin. An n value of 1 sets the tab at the left margin. A maximum value of n sets the tab one character to the left of the right margin. Therefore, n is the character position relative to the left margin, not the actual column number.

The following shows the location of tabs for various values of n.

Column	1	2	3	4	5	6	7	8	9	10
