The QL 420 Plus direct thermal mobile printer delivers print widths up to 4.09" (103.9 mm). In addition to offering the rugged construction, user-friendly options, and flexible QuickLink connectivity that have made Zebra's QL 420 and other QL series printers so popular, the enhanced QL 420 Plus printer is specially designed for complex mobile printing applications. It's built to handle increased levels of wireless security and to process complex labels up to four times faster, making it ideal for the secure transfer of sensitive data such as price lists, customer information, and medical records.

The QL 420 Plus is ideal for many applications, including pick tickets, forklift-mounted printing, customer pickup, shipment labeling, inventory updates, meter reading receipts, delivery verification invoices, and gas and utility inspection documentation.
