SB - Scalable or bitmap fonts 

SB [ 

n

 ] [;] 

n

 : font category selection 

• 

This command enables you to restrict the range of selectable fonts to scalable fonts and the stick font only. 

• 

n

 can be 0 or 1.  If 

n

 = 0 you may only select scalable fonts (or the stick font).  If 

n

 = 1 you may select any 

type of font. 

• 

An SB command can alter the current standard and alternate font selections. 

• 

Setting 

n

 to 1 allows the selection of  bitmapped fonts and has the following side-effects: 

• 

Bitmap characters cannot be edged. 

• 

Bitmap characters can only be printed in orientations of 0°, 90°, 180° or 270°. 

• 

The SL (character slant) command is not applied to bitmap fonts. 

• 

Bitmap font character sizes are approximate only. 

• 

The DF and IN commands set n to 0, - only scalable fonts and the stick fonts may be selected. 

• 

The FI and FN commands implicitly set n to 1 if you use either of them to select a bitmap font. 

• 

If you omit n from the command,  only scalable fonts and the stick font may be selected.  This is equivalent 
to an SB0; command. 

• 

The default setting is scalable fonts and stick font only. 

ES - Extra space 

ES [ 

width

 [,

height

]] [;] 

width

 : factor by which character spacing is changed. 

height

 : factor by which line spacing is changed 

• 

This command enables you to adjust the space between label characters and lines. 

• 

width

 specifies the factor by which to increase or decrease the character spacing.  Positive numbers specify 

an increase and negative numbers a decrease. 

• 

height

 specifies the factor by which to increase or decrease the line spacing.  Positive numbers specify an 

increase and negative numbers a decrease. 

• 

If you use the command without parameters, no extra space is used when labels are printed.  This is 
equivalent to ES0,0; 

• 

An ES command remains in effect until another ES command is executed,  a DF or IN command is executed or 
the printer is reset,  either with the EscE command or from the control panel. 

TD - Transparent data 

TD [ 

mode

 ] [;] 

mode

 : normal or transparent data mode. 

• 

This command enables you to specify whether control characters should perform their normal function or 

should be printed.
