Vertical Tabs
Vertical tab stops are associated with lines, not absolute physical positions. Changing line spacing will change the physical position of the tab stops.
Vertical Tab | VT |
Causes the current line to be printed, and then advances the paper to the next vertical tab stop. If no vertical tab stops are set, then a line feed is done instead. If “Auto CR” is set to “On” in the interface setup menu, a carriage return will also be performed.

Set Vertical Tab Stop | VTS |
(or) | ESC J |
(or) | ESC 3 |
Sets a vertical tab stop at the current line. The tab stop is associated with the active line, not an absolute physical position. Changing line spacing will change the physical position of the tab stop.
The tab stop set by this escape sequence will be added to previously set tab stops. If this is not desired, the old tab stops should first be cleared.

Set Vertical Tab Stops |
| ESC [ n1 ; n2 ; ... nx v |
Sets new vertical tab stops at line n1, n2, n3, etc. 1³n³255. The tab stops are associated with lines, not absolute physical positions. Changing line spacing will change the physical position of the tab stops. The first line is line one.
The tab stops set by this escape sequence will be added to previously set tab stops. If this is not desired, the old tab stops should first be cleared.
Example: The following escape sequence will set vertical tab stops at line 7, 13, and 25. If line spacing is 6 lpi, this will result in tab stops one inch, two inches, and four inches from the top of the form.
