CF - Character fill mode 

CF [ 

fill

 [, 

pen

 ]] [;] 

fill

 : the fill pattern used to fill characters 

pen

 : the pen used to edge characters  

• 

This command determines how characters are edged and filled. 

• 

Only scalable fonts can be both filled and edged - bitmap fonts and the stick font cannot be edged and 

can only be filled with raster fill, shading or PCL cross-hatch patterns.  Scalable characters can be filled 
with any pattern specified by the FT command. 

• 

Permissible values of 

fill

 are 0, 1, 2 and 3.  If 

fill

 = 0 characters are filled with a solid fill and edged.  If 

fill

 = 1 characters are edged but not filled.  (Bitmap characters and stick font characters are filled as they 

cannot be edged.)  If 

fill

 = 2 characters are filled using the current fill type,  but not edged.  If 

fill 

= 3 

characters are filled,  using the current fill type and edged. 

• 

pen

 can be either 0 or 1.  A value of 0 specifies the edging pen to be white;  a value of 1 selects the 

black pen for edging.  If no pen is specified in the instruction the current pen,  as selected with the SP 
command,  is used. 

• 

The width of the edging pen is proportional to the character's point size. 

• 

The fill line width used for cross hatch patterns is set with the PW command. 

• 

If you omit both parameters solid fill and the white edging pen are selected - this is equivalent to CF0.0; 

• 

If the command is not used all characters are solid and unedged. 

• 

A CF command remains in effect until an IN command is used to initialize the printer,  a DF command is 

used to restore the default settings or another CF command is invoked.

SI - Set absolute character size 

SI [ 

width

, 

height

 ] [;] 

width

 : the width in centimeters of printed characters 

height

 : the height in centimeters of printed characters 

• 

This command allows you to specify the size of the characters that you print with the LB instruction in 
centimeters. 

• 

width

 specifies character width and is a clamped real number.  Negative values of width produce right-to-left 

mirror image characters. 

• 

height

 specifies the height of a capital letter and is a clamped real number.  Negative values of height 

produce upside-down mirror image characters. 

• 

If you change character size, the line width used to draw stick font characters may also change. 

• 

If you omit the parameters,  the character size is as specified by the most recent SD or AD command. 

• 

If an SB1; command has previously  been issued,  printed characters may not be exactly the size that you 
specify. 

• 

If an SB1; command has been issued,  specifying a negative value will not produce mirror image characters.
