Set vertical channel tab stops
Escbnm1m2m3...NUL (27)(98)nm1m2m3...(00) <1Bh><62h>nm1m2m3...<00h>
• 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.

Select vertical tab channel
Esc/n (27)(47)n <1Bh><2Fh>n
• 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.

VT (11) <0Bh>
• 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.
