Scale Adjustment Factor
Specifies a scale factor that will be applied to the geometry after it is generated by the print engine. This property can be used to compensate for inaccurate printer output. For example, if you request an 11 x 17 inch print, but the printer produces an 11.0 x 16.8" print, you can specify a scale adjustment factor of (1.0, 1.0119) to increase the scale of one axis. The default is 1, 1.
