Gets or sets the scale factor used to scale images before printing.
Low resolution images that need to be sized up to fit the target physical bounds can be scaled either by the printer driver, or by C1DocumentSource. When this property is 1 (the default), all scaling is done by the printer.On some printers this can lead to visible distortions.To avoid this, set this property to a value greater than 1 (e.g. 2, 3 or 4), which will cause C1DocumentSource to scale the image before sending it to the printer, and may help reduce the distortions.The specific value depends on the printer, and can be selected by trial and error.

Note that this does not affect the final printed size of the image, it only controls how the image is resized.
