Set Vertical Tab Channels

Set Vertical Tab Channels
ASCII Code ESC / m
Hex Code 1B 2F m
Dec Code 27 47 m
Purpose The value for m specifies the number of the tab sets being
changed; these sets of tabs are called vertical formatting unit
(VFU) channels.
Where:
0 <=
m <= 7
Comment You must use this command to select a tab set (VFU channel)
other than set 0; the VT (tab vertically) command then uses the
settings for the selected channel.
You can select from eight sets of tabs (VFU channels).

Purpose Sets vertical tab positions (in the current line spacing) at the
lines specified by
n

to n
k
, as measured from the top-margin
position.
The values for n must be in ascending order; a value of n less
than the previous n ends tab setting (just like the NUL code).
Where:
0 <=
k <= 16
1 <= n <= 255

Comment Changing the line spacing does not affect previous tab settings.
The tab settings move to match any subsequent movement in
the top-margin position.
Send an ESC B NUL command to cancel all tab settings.
A maximum of 16 vertical tabs can be set.
The printer stores all tab settings, even if outside the printing
area; if you increase the page length to include previously set
tabs, you can move to those positions with the VT (tab
vertically) command.
Sending the ESC B command clears any previous tab settings.
