The RL4e (4-inch/102mm) is a durable direct thermal printer with a rugged design and reliable performance that will continue to operate long after other printers have failed. We’re so confident in the quality and long-term reliability of this rugged printer that we include a 2-year warranty free of change. The RL4e improves efficiency and productivity by allowing workers to print and apply barcode labels directly at the point of application. Using an RL4e to print on-demand labels also eliminates the danger of mixing up batch-printed labels and saving thousands of dollars in potential shipping errors.
