HP LaserJet 4250 Series

The LJ4250 series are fast mono laser printer handling A4 / letter page size. The LJ4250 runs at up to 45 pages per minute. Output quality is high with a resolution of 1200 dpi at full engine speed.

The built in processor and memory offloads tasks from user computers quickly, letting them get on with work. The LJ4240n has a 460MHz RISC processor matched by 48MB or 80MB of memory to give performance matching workgroup needs.

The series is an updated version of the LJ4200 / 4300. The LJ4250 has a faster processor and more memory on the formatter. There is a USB and an IEEE 1284 parallel port making it easy to connect to individual computers. The LJ4250n models have an embedded JetDirect ethernet print server so network models still have two free EIO slots.

The LJ4250s capabilities can be expanded using two Compact Flash slots to add fonts, e-forms, barcode printing, job accounting and secure printing. There are a range of trays, a duplex unit, envelope feeder and stacker / stapler.
