CHAPTER 4 HP-GL/2 - 49
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.
