I have an HP LaserJet 9050dn for sale. It's a tabloid-sized black and white laser printer that prints on 11" x 17", 8.5" x 14", 8.5" x 11", and various other custom sizes in between. It has two main (enormous) paper trays, one manual paper tray, a built-in duplexer, and prints 55 pages per minute.

The printer is in good working order, has plenty of toner left, two network cards, and has been upgraded to the latest firmware version.

It's large enough that it probably will not fit in anything but a truck.

This printer costs $3,879.99 new (see http://www.staples.com/HP-LaserJet-9050dn-Printer/product_585206 ). This particular model has printed 196,436 letter pages and 239,753 pages total, which for these models is on the low end.
