Vertical Tabs
Vertical tab stops are associated with absolute physical positions, not with lines. The
tab stops are set relative to the current line spacing, but subsequent changes in line
spacing will not affect 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:
On" is selected in the "Setup: INTERFACE" menu, a carriage return will also be
performed.
Control code: VT
Hexadecimal: 0B
Set Vertical Tab Stops ESC B n1 n2 ... nx NUL
Clears all currently set vertical tab stops, and sets new tab stops at line n1, n2, n3, etc.
1≥n≥255. The tab stops must be presented in ascending order. The NUL character,
or any tab stop value less than the preceding one, terminates the sequence. The tab
stop settings are based on the current line spacing. Changing the line spacing after
the tab stops are set will not affect the position of the tab stops. The first line is line
one.
ESC B NUL or ESC R will clear all currently set vertical tab stops, leaving no
vertical tab stops set.
Example: The following escape sequence will set vertical tab stops at line 7, 13, and
25. If line spacing is currently 6 lpi, this will result in tab stops one inch, two inches,
and four inches from the top of the form.
Escape Sequence: ESC B 7 13 25 NUL

41, etc. Clears all currently set vertical tab stops.
