Lexmark T640dn Toner

Cartridge prices starting at $114.95

What sets the Lexmark T640DN apart from the other Lexmark printers is that it features 2-sided printing. This helps printer users save paper costs. But aside from this, it also comes with a powerful 400MHz processor and standard 64MB RAM (expandable up to 576MB) for fast printing. Ethernet is standard, while wireless connectivity is optional. To save on printing costs, a more affordable toner cartridge is available here at Inkjets.
