If you need a workhorse that can keep up with your small business or team within a larger organization, a workgroup HP LaserJet 9500hdn Printer is an obvious choice. Designed to juggle multiple print jobs, these systems have faster processors, more memory, and print engines that are capable of churning out more than 20 pages per minute. But these $400-and-up printers are more than souped-up personal lasers; they offer workgroup features, such as network printing, high-capacity toner cartridges, and larger paper input and output trays.
