The fitted cutter is rated for 2,000,000 cuts, giving high-cycle POS and labeling environments a measurable service interval. Serial and USB interfaces cover connectivity, and the unit ships with a power supply drawing from AC supply or power adapter. The desktop chassis measures 8 inches tall by 5.5 inches wide by 5.8 inches deep and weighs 4.19 lb. A one-year limited warranty applies.
