Advances the simulated print head to the next vertical tab
position selected by ESC /.
If no vertical channel was selected, channel 0 is used. If no
vertical tabs were set, the paper advances one line.
The simulated print head moves to the left margin. If a tab
position is on the current line, the paper is moved to the next
tab position. If there are no tab positions between the current
line and the end of the form, the paper is moved to the top of
the next form. If the printing crosses the page boundary, the VT
command causes the paper to move to the top of the next form.
This code cancels all single line print attributes.

Sets up to 16 vertical tab positions.
Where:
n = 1 through 255
k = 1 through 16
n1 through nk specify the line number for the vertical tab(s), up
to a maximum of 16 tab positions. NUL must end the sequence.
To clear the tab settings, send ESC B NUL (1B 42 00).
The values of n range from 1 through 255 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 . If the
value of 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
command, ESC /, and the channel loading command, ESC b.)
