Using Tabs 

Set horizontal tab stops 

EscDn1n2n3...NUL 

(27)(68)n1n2n3...(00) 

<1Bh><44h>n1n2n3...<00h> 

• 

This command enables you to set up to 32 horizontal tab stops based on the current character width. 

• 

The character width setting is determined by the combination of the current pitch (10 or 12 characters 
per inch) and the current character mode (condensed, normal or double-width).  If proportional 
spacing is being used the character width is based on a pitch of 10 characters per inch. 

• 

The tab stops must be set in ascending order.  If you invoke the command with the tabs in any other 
order all horizontal tab settings are cleared. 

• 

The value of 

n

i

 must be in the range 0 to 255. 

• 

Once you have selected the tab settings they remain fixed - their position does not change if you 

change the character pitch or character width settings. 

• 

To set up a group of equally spaced tab stops use the 

Esc e 0 

command. 

• 

Esc D 0

 clears all horizontal tab settings. 

• 

The default tab stop settings are at every eig hth column, starting at the ninth column.  The default 

column width is 1/10". 

• 

The default settings are adopted when the printer is first switched on or when you perform a reset with 

the 

Esc @

 instruction. 

• 

You can move the print position to the tab stops using the 

HT

 control code. 

LPRINT CHR$(27); CHR$(68); CHR$(10); CHR$(20); CHR$(0);  

'Set tab stops at columns 10 and 20. 

Horizontal tab 

HT 

(09)  

<09h> 

• 

The 

HT

 control code (ASCII code 9) moves the current print position one tab stop to the right. 

• 

The command is ignored if there are no tab stops to the right of the current print position or if the next 
tab stop is beyond the right margin. 

LPRINT CHR$(9); 'Tab 

Set vertical tab stops 

EscBn1n2n3...NUL 

(27)(66)n1n2n3...(00) 

<1Bh><42h>n1n2n3...<00h> 

• 

This command enables you to set up to sixteen vertical tab stops based on the current line space 
setting. 

• 

The tab stops must be set in ascending order.  If you specify the tab settings in any other order, any 
settings made with a previous 

Esc B

 command are cleared. 

• 

The value of 

n

i

 must be in the range 0 to 255. 

• 

Vertical tab settings are not affected by subsequent changes in the line spacing setting. 

• 

To set up a group of equally spaced tab stops use the 

Esc e 1 

command. 

• 

Esc B 0

 clears the vertical tab settings set with a previous 

Esc B

 command. 

• 

You can move the print position to the tab stops using the 

VT

 control code. 

LPRINT CHR$(27); CHR$(66); CHR$(12); CHR$(24); CHR$(0);  

'Set tab stops at lines 12 and 24. 

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.
