Speed and Quality of Printers
Speed of printer is determined by PPM (Page Per Minute). Obviously, the higher the PPM of a printer, the faster or more pages it can print. (E.g. 17 ppm)
The quality of print-outs depends on DPI (Dot Per Inch) of the printer. The higher the DPI of a printer, the better the quality of output. Its simply because it packs more dots into an inch. (E.g. 4800x1200 dpi)
While those are true hardware architectures, you can also tweak the speed and quality of output via software configurations.
