Horizontal Tabs
Horizontal tab stops are associated with columns, not absolute physical positions. Changing character
spacing will change the physical position of the tab stops. Default tab stops are set at every eighth column,
i.e. column 9, 17, 25, 33, 41, etc. If different tab stops are to be set, the default tab stops should first be
cleared.
Horizontal Tab HT
Advances to the next horizontal tab stop. If no tab stop exists between the active column and the right
margin, the HT will be ignored. Default tab stops are set at every eighth column, i.e. column 9, 17, 25, 33,
41, etc. Different tab stops may be set with ESC H, ESC 1, or ESC [ n1 ; n2 ; ... nx u.

Set Horizontal Tab Stop HTS
(or) ESC H
Sets a horizontal tab stop at the current print position. The tab stop is associated with the active column, not
an absolute physical position. Changing character spacing will change the physical position of the tab stop.
Default tab stops are set at every eighth column, i.e. column 9, 17, 25, 33, 41, etc. The tab stop set by this
escape sequence will be added to previously set tab stops, including the default tab stops. If this is not
desired, the old tab stops should first be cleared.
