The Okidata C5100 is a very impressive laser printer for the amount you will pay for it. While both the Okidata 5100 and Okidata C5150 are big printers, this just increases thier efficiency, allowing them to print up to twenty black and white pages per minute as well as twelve color pages per minute! The flexability of these laser printers is stretched to have four individual inks which allows you run out of one color and continue printing with the other three. To make this laser printer even more afforable, buy the Okidata inks online and look for a generic brand.
