CHAPTER 4 HP-GL/2 - 42 
AD - Define alternate font 
AD [ attribute, value ] [..] [;] 
attribute : a font attribute to be defined 
value : the value of the attribute 
   This command allows you to define the alternate font and its attribute. 
  attribute takes a value from 1-7.     
1 = symbol set,    2 = spacing,    3 = pitch,    4 = height,  5 = posture,  6 = stroke weight and 7 = typeface. 
  value selects an option for the specified attribute. For further explanation about attribute values    see the 
previous SD command. 
  If the defined font is not available, another font is selected that matches the defined font's specified attributes 
as closely as possible.    The symbol set attribute has the highest priority for matching    and typeface has the 
lowest. 
  If you omit all parameters,    the default alternate font attributes are used.

SS - Select standard font 
SS [;] 
  This command allows you to select the standard font,    as defined by the SD command.    All subsequently 
printed labels will appear in the standard font. 
  The SS command is equivalent to including the SI control code (ASCII 15) in a label. 
  The default standard font is the HP-GL stick font. 
  The font remains current until the printer is initialized with an IN command, until the default conditions are 
resorted with the DF command    or until an SA command is used. 
 
SA - Select alternate font 
SA [;] 
  This command allows you to select the alternate font,    as defined by the AD command.    All subsequently 
printed labels will appear in the alternate font 
  The SA command is equivalent to including the SO control code (ASCII 14) in a label. 
  The font remains current until the printer is initialized with an IN command,    until the default conditions are 
restored with the DF command    or until an SS command is used.
