The Laserjet 8000 printers are excellent high volume printers that have given us very few problems. We have 4 of the printers that print up to 80,000 pages a year each without paper jams or printing faults. The toner cartridges are easy to change, only taking a few minutes to replace. The actual print speed is adequate at around 20 pages a minute.
The networking of the printers is very easy using the jet-direct software to add new printer ports, although care should be taken if manually editing the TCP/IP address of the printer.
Overall, I would recommend the printer for workgroup printing where high volume and reliability is required, especially when A3 printing is required in conjunction with A4 printing.
