Chapter 14: Epson - Standard Function

Vertical tabulators
The command ESC D NUL clears all horizontal tabs, including the
standard tabs. If the printer is switched off and on, the standard
tabs are available again. If no other tab is set up to the end of line,
the tab skip command is ignored. When the printer is switched on
the left margin equals the most left position. If you change left mar-
gin the position of the tabulators will change accordingly.
The maximum permissible values for tab positions can be seen
from the following table.

No vertical tabs are set when the printer is switched on. Up to 16
vertical tab positions can be set; the positions are defined as line
numbers.
They must be entered in ascending order and end with a NUL cha-
racter. The parameter n
1
indicates the line number of the first tab, n
2
to n
k
accordingly the line numbers of the other tabs to be set.
Up to 16 vertical tabs can be defined (n

). ESC B NUL deletes all
vertical tabs.
If the command VT is entered without any defined tab position, a
line feed is executed.
The actual position of a tab mark depends on the actual line spacing
when loading the vertical tabs and does not move when line spa-
cing is changed (absolute position). With the skip command for the
vertical tabulator the paper is transported to the next tab position.
