
You can set up to eight different sets of vertical tab stops and select any of these sets for use at any time.
Each set of tab stops is called a channel - channels are numbered from 0 to 7.
 Channel 0 normally holds the settings you have selected with the
Esc B
command, or equally spaced tab
settings that you have set with the
Esc e 1
command. However, you can also set the channel 0 tab settings
using the
Esc b
command.
 To set the tab stops held in channels 1 to 7 you must use the
Esc b
command.

This command enables you to set up to sixteen vertical tab stops for each channel based on the current line
space setting.
 n is the channel number whose tab stops are to be set.
 m
i
specifies the tab based on the current line space setting.
 The value of m
i
must be in the range 0 to 255.
 The tab stops must be set in ascending order. If you specify a channel's tab settings in any other order, any
previous settings made for that channel are cleared.
 Vertical tab settings are not affected by subsequent changes in the line spacing setting.

Esc b
n
0
clears the vertical tab settings set for channel n.
 You can select a channel using the
Esc /
command and move the print position to its tab stops using the
VT
control code.

 This command allows you to select a set of vertical tabs (or channel) that you defined using the
Esc b
command.
 All subsequent vertical tab commands use the selected tab channel's settings.
 n must be in the range from 0 to 7.
 The default channel is channel 0. Channel 0 is the current channel when the printer is first switched on or
after a reset with the
Esc @
command.
 There are no default vertical tab settings for any channel.


The
VT
control code (ASCII 11) moves the current print position one vertical tab stop down the page. The
current vertical tab channel's settings are used.
 If you have not previously selected a vertical tab channel with the
Esc /
command, channel 0, the default
channel is used.
 If you have not set any vertical tab stops for the current channel with either the
Esc B
,
Esc b
,
or Esc e 1
commands, the print position is moved down one line using the current line space setting.
 If there are no tab stops below the current print position a line feed is performed.
 If no tab stops have been set a carriage return and line feed are performed.
