Xerox Phaser 6500DN ($350-$400) Color double-sided letter-size laser printer. Not as heavy duty as the Phaser 4600 for high volume printing so don't use this printer for high volume.

Xerox Phaser 7760 (out of production) This color tabloid-size (11X17) printer was one of the best large format printers ever made. Great for high volume print environments and printing.
Toshiba e-Studio 3555c Multi Function Printer (~$6000-$20,000 depending on installed options) This copier, printer, scanner, business grade multi function printer does it all. It prints legal, letter, tabloid, double sided, from a usb drive, it does color, it does black and white, it scans to email. There are additions for stapling and collating. However, the breadth of this functionality comes at a hefty price.
Xerox Workcentre 7845 Multi Function Printer (~$8000-$21000 depending on installed options) Very similar to the Toshiba but the admin panel and software has a lot more options including firewall and file encryption.
Xerox Phaser 3600DN (out of production) Black and white double-sided printer. This printer is ok for a small office, but really recommended for a single user environment.
Xerox Phaser 3610DN ($500-600) Replacement for 3600DN. Black and white double-sided printer. This printer is ok for a small office, but really recommended for a single user environment.

Xerox Phaser 7100DN ($1600-$2000) Color double-sided laser printer. (Tabloid 11X17) This printer has a considerably lower duty cycle than the 7500DN and the cartridges for this printer are small and expensive, so this printer is really only recommended for individual low volume print environments. Be forewarned that if you use this printer in a high volume environment, you will not only be drastically decreasing the lifespan of this printer, but you will be paying obscenely through the nose for toner. Higher duty cycle printing should use the 7500DN.
