vertical tabs were set, the paper advances one line.
The logical print head moves to the left margin. If a tab position

To clearthe tab settings, send ESC B NUL (1B 42 00).
Comment The values of
n
range from 1 through 255 (hex 01 through FF)
and must be in ascending order. The distance of each tab stop
from TOF is the current line spacing times the number of lines
given in
n
.Ifthevalueof
n
exceeds the form length, commands
to move to that tab position are ignored.
If values of
n
are not in ascending order, the sequence up to and
including the out-of-sequence number is ignored, and the rest of
the load is processed. Skip over perforation is ignored.
This command always sets channel 0. You can clear channel 0
by sending ESC B NUL. (See also the channel selection
