Purpose Sets vertical tab positions at the lines specified by
n
1
to
n
k
(in
the current line spacing) in tab set
m
, as measured from the
top-of-form position.
The value for
m
specifies the number of the tab sets being
changed; these sets of tabs are called vertical formatting unit
(VFU) channels.
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 <=
m
<= 7
1 <=

Comment Up to eight sets of tabs can be set.
Send the ESC / command to select a VFU channel other than
channel 0; the VT (tab vertically) command then uses the
settings for the selected channel.
Changing the line spacing does not affect previous settings for
vertical tabs.
Sending the ESC b command clears any previous tab settings
in that tab set.
Send an ESC b
m
NUL command to cancel all tab settings in
the tab set
m
.
A maximum of 16 vertical tabs can be set in each VFU channel.
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.
