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.
