Lexmark CS410dtn Color Laser Printer
Lexmark built this machine for small to medium size work environments giving users high quality resolution and print speeds that can reach over 30 ppm. That speed combined with a 1200 dpi resolution that can be cranked all the way up to 2400 makes it ideal for repeated use by multiple users.
The CS410dtn is able to handle a workload of around 75000 prints a month before you need to start worrying about replacing toner cartridges. You get duplex capabilities here as well, with pretty respectable print speeds there too, topping out at around 15 ppm.
With all of this work capability, it better have darn good paper capacity as well. You're in luck, because Lexmark's machine comes with a 550 sheet dual tray and a 100 sheet dual purpose feeder. If that's not enough simply attach another 550 page tray for a total of 1200 pages of paper, ranging in size from 3x5 to 8.5x14.
