• 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.

• 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.

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.

Escpn (27)(112)n <1Bh><70h>n
• This command allows you to turn proportional spacing on or off.
• Setting n to 1 turns proportional spacing on. Subsequent text is printed proportionally spaced.
• Setting n to 0 turns proportional spacing off. Subsequent text is printed monospaced.
• When you specify the value for n you can use the character codes for ‘0’ and ‘1’ (48 and 49) instead
of 0 and 1.
• Selecting proportional spacing cancels condensed character mode.
