BIOS Magazine posted a review on the Dell Laser Printer 1720dn

Home and business customers alike continue to look for both high-performance and high-quality output from today's business laser printer products. At the same time they expect a printer that continues to deliver real print budget benefits, today and tomorrow. Dell's Laser Printer 1720 and Laser Printer 1720dn laser printers continue the high performance/low price standards set by their predecessor products, the Dell Laser Printer 1710 series, offering improved features and performance while continuing to drive down print costs. If you're in the market for a solid monochrome workhorse for networked business use, you can't go much wrong with the Laser Printer 1720dn. And if you don't need duplex or Ethernet connectivity, the Laser Printer 1720 is even better value for money.
