The HP LaserJet 4300dtn is part of the 4300 series which is claimed to supersede the 4100 line of laserjet printers. Its line was introduced as the improved version of its predecessor, touting a print speed of 45 pages per minute. The unit comes with 80MB memory which can be upgraded up to 416MB. Combining a monthly-duty cycle of 200,000 pages plus a high-performance engine, these define the printer as a suitable workhorse to support medium-sized workgroups. The consumable it requires, particularly the HP Q1339A (39A) toner cartridge comes with a much higher-yield of up to 18,000 pages. Media handling can cope with a busy environment through its maximum input capacity of 1100 A4 sheets.
