Zebra QLn320 Direct Thermal Mobile Label Printer

Zebra’s popular QL™ family of direct thermal mobile label printers has built a highly satisfied following based upon its proven drop-resistant durability; user-friendly, productivity-boosting features; and easy integration. As Zebra’s third generation of QL printers, the QLn™ series extends these QL-platform benefits to the “nth” power—whether you choose the QLn320™ for 3-inch-wide printing.

A new seamless, one-piece design and tempered-glass display join the printer’s rubber-infused over-molding to make the lightweight printer even more durable. The Zebra QLn320 printer can boost your operation’s productivity through a larger, sharper, easier-to-navigate display; faster, higher-quality printing; a variety of proactive alerts that help keep working printers in employees’ hands; and many convenient charging accessories. And your IT department will find the QLn 320 easier to integrate into existing environments with such features as Zebra Global Printing (coming soon), improved network performance, and ZebraLink™ support. Also prolong printer uptime and enhance operations productivity with remote Ethernet-connected printer, battery, configuration, and firmware management, all supported by ZebraLink™ tools.

Easier and more efficient to use
Multiple enhancements deliver significant operations advantages over the previous-generation QL and QL Plus™ series mobile printers.

Easier to Use
Reduce training requirements and speed user adoption. Increase worker productivity and process efficiency.

  • Easy-to-read display with larger, higher-resolution screen
  • Easy-to-navigate controls and interface, including help menu and alert messages
  • Intuitive peeler operation
  • Easy to carry and store with smaller, lighter printer design
  • Faster, higher-quality printing with lower power use, through new Power Smart Print Technology™
  • Higher performance
    - Faster processing and throughput
    - Increased memory that handles printer’s advanced functions and future firmware improvements, and stores more complex fonts, graphics and images
  • New, convenient charging accessories increase user and operations efficiencies

Longer Printer Uptime
Improve operations productivity and reduce costs associated with downtime through fewer printing interruptions.

  • Prevent associates from being stuck printerless in the middle of their work. The printer enables proactive maintenance by displaying printer alert messages, smart battery charge and health status, and printhead cleaning reminders and how-to’s.
  • Avoid the downtime and costs of unnecessarily sending the printer away for servicing. Many issues can be remotely diagnosed and resolved (including firmware updates, configuration changes, and adding new fonts or graphics) over an Ethernet connection.

Manage and Maintain
New features in the Zebra QLn320 label printer make it easier and quicker to integrate into your existing network and printer environment, anywhere in the world, with no changes to software or network infrastructure needed. They help save IT time and costs—as do easier printer management and other features.

Easier to Integrate

  • Backwards compatibility with QL and QL Plus lets you upgrade to the QLn 320 without changing media or label formats. It also allows mixed networks of QL/QL Plus and QLn products, as does the QLn printer’s inclusion of the legacy CPCL programming language.
  • Inclusion of ZPL® X.16 programming language (coming soon) simplifies integration with Zebra
    desktop and tabletop printers.
  • With Zebra’s Unicode™ UTF-16-compliant Global Printing Solution (coming soon) with right-to-left printing capability, print in the native language of most countries around the world, and print multiple languages on a single label.
  • Integrate and use the printer in a variety of physical environments and conditions thanks to its durable design.

Easier to Manage

  • Rapidly configure, monitor and control Zebra printers on your network—maximizing uptime to get the most from your investment—with ZebraLink™ tools like the Zebra Setup Utility (for single printer setup), ZebraNet™ Bridge Enterprise for global centralized printer management, ZebraDesigner™ Drivers (for Windows® based printing), ZebraDesigner Pro (for label design), ZebraLink Multiplatform SDK and Smartphone Utility (for printing from mobile terminals and smartphones), and (coming soon) ZBI 2.0™ programming for customizing the functionality of the printer, including connecting to scanners, scales, and other peripherals.
  • Also manage specific, local printer and battery issues remotely over a wired IP network via a Zebra Ethernet Cradle—keeping printers in service longer and reducing “no problem found” returns.
