CHAPTER 4 HP-GL/2 - 16
 With type 1 scaling you can specify the percentage of unused space that is to lie below, or to the left of,
the isotropic area.
 left specifies the percentage of unused space you want to lie to the left of the isotropic area and can be from 0
to 100. If you do not specify the value for left, it is automatically set to the default value = 50%.
 bottom specifies the percentage of unused space you want to lie below the isotropic area and can be from 0 to
100. If you do not specify the value for bottom, it is automatically set to the default value = 50%.

 You must either specify both left and bottom, or specify neither. However, the printer can only use one of
these two parameters at a time, depending where the extra space is on a page. ¥
 If you do not specify a percentage for unused space to the left or at the bottom, the isotropic area is centred
in the rectangle defined by P1 and P2.
 Type 2 scaling (point factor scaling) specifies the ratio of graphics units to user units and sets user units
coordinates for P1.
 X
factor
specifies the number of graphics units that comprise a single user x-axis unit.
 Y
factor
specifies the number of graphics units that comprise a single user y-axis unit.
 Valid values for X
factor
and Y
factor
are real numbers.
 An SC command remains in effect until another SC command is issued, until default settings are restored
with the DF command or until the printer is initialized with an IN command.
