HP LaserJet Pro 4003dn Hi-Speed Mono Laser Printer

This is HP's workhorse mono laser printer for busy offices that need speed and volume. It's a print-only unit, but it's fast — 40 ppm — and built to handle a serious monthly workload. The trade-off is no wireless, but the Gigabit Ethernet and USB connectivity make it a solid choice for a networked team. If you need to churn out documents all day without babysitting it, this is a reliable pick.
