What print quality settings are available and when should I use each?

Three print quality levels are available: Fast (for draft copies at maximum throughput), Normal (optimized for best line quality with fastest throughput), and Best (for best quality for images and renderings). With Best mode selected, you can choose maximum detail mode to increase resolution to 1200x600 dpi. Different resolutions apply depending on whether your content is optimized for Line Drawing/Text or Images. (Page 10)
