Rasterized Quality Factor
The ratio of printer driver resolution to raster resolution, as a percentage, when printing in rasterized mode. That is, 100 means that rasterized prints should be made at the driver resolution. Setting it to 50 results in rasterized prints made at half the available resolution, which may be desirable if print's file size is a bigger concern than output quality.
Because prints containing fine line work could be badly decimated if not rasterized at device resolution, reducing the rasterized quality factor is not recommended.
