A new printer recently showed up at work. There are an abundance of possible drivers for it applicable to my system (Windows 7, 64 bit) including PCL5, PCL5e, PCL6 and UFR II.
I'm familiar with PCL, but not UFR II, although the ever-helpful Wikipedia told me it stands for "Ultra Fast Rendering".
What (if anything) is the advantage of using the UFR II driver over one of the PCL variants?
