Datamax-O’Neil built its reputation on rugged and reliable portable receipt printers and has now used this expertise to design the industry’s most rugged portable label printer. The RL4 is a durable 4-inch (102mm) 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. That’s double what the competition offers.
Anybody who’s ever been in a warehouse knows that when shipments are processed more quickly and effectively, productivity is increased and errors are reduced. The RL4 improves efficiency and productivity by allowing workers to print and apply barcode labels directly at the point of application. Using an RL4 to print barcode labels on-demand labels also eliminates the danger of mixing up batch printed labels and saving thousands of dollars in potential shipping errors. The portable printer can even be mounted on fork trucks for added convenience and versatility.
We’ve made integration easy. Replace existing label printers using Datamax-O’Neil’s language emulations. The RL4 is compatible with most popular warehouse management software programs, independent label design programs and remote management packages.
