Longer Printer Uptime

Improve operational productivity and reduce costs associated with downtime through fewer printing interruptions.

  • Monitor and manage the printer remotely using the Windows PC-based AirWatch Connector
  • 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.
  • 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.

Lithium-Ion Charging Accessories

The QLn420 charging and Ethernet cradle charges the battery — a neat and orderly solution to keep batteries in the printer.

Connect QLn printers to your wired Ethernet network via the QLn Ethernet cradle to enable easy remote management by your IT or operations staff — helping to ensure each printer is operating optimally and ready for use. The Ethernet cradle can communicate over 10 Mbps or 100 Mbps networks using auto-sense.

The printer remains fully functional so you can print while it is in the cradle. The cradle’s LED lights indicate DC power and Ethernet-link status.

Remote printer management over your Ethernet allows:

  • Battery management for monitoring battery health. Knowing each battery’s lifespan stage simplifies central management of your spare-battery pool.
  • Firmware management for updating printer firmware, eliminating the need for IT staff to travel to the local user site, or for the printer to be sent back to a central location for updating.
  • Print management for updating templates, fonts and graphics in order to print new label formats.
  • Device management for updating startup (e.g., config.sys), WML (front panel) or HTML (browser) files to enhance or change configuration and status collection.
  • Network management for updating encryption keys or certificate files to maintain the highest level of security.
  • Problem resolution and troubleshooting local printer issues that may otherwise require the printer to be sent in for repair.
  • Ability to manage Bluetooth printers, which traditionally have been off-network.

802.11 n

802.11n is an amendment that improves upon the previous 802.11 standards by adding multiple-input multiple-output antennas (MIMO). 802.11n operates on both the 2.4 GHz and the lesser-used 5 GHz bands. Support for 5 GHz bands is optional. It operates at a maximum net data rate from 54 Mbit/s to 600 Mbit/s. The IEEE has approved the amendment, and it was published in October 2009.Prior to the final ratification, enterprises were already migrating to 802.11n networks based on the Wi-Fi Alliance's certification of products conforming to a 2007 draft of the 802.11n proposal. The 802.11n amendment includes many enhancements that improve WLAN range, reliability, and throughput. At the physical (PHY) layer, advanced signal processing and modulation techniques have been added to exploit multiple antennas and wider channels. At the Media Access Control (MAC) layer, protocol extensions make more efficient use of available bandwidth. Together, these High Throughput (HT) enhancements can boost data rates up to 600 Mbps – more than a ten-fold improvement over 54 Mbps 802.11a/g (now considered to be legacy devices).


203 DPI

Barcode printing in 203 DPI is great for text, numbers, and codes, but may appear a bit grainy or pixelated. You can improve the print quality of a barcode printed in 200 DPI by making the barcode physically larger on your label, but you may not have enough space to do this on your label. If you decide to do this, please note that each barcode must be scaled proportionately, since the aspect ratio of each barcode is strictly defined by each barcode symbology.203 DPI Printers are the fastest barcode printers and are suitable for high volume applications. 

Printing Method

Direct Thermal

Direct thermal printing requires a heat sensitive label material. The print head elements come into direct contact with the heat sensitive material where the heat from the elements causes a color change in the material to create the printed image. If an organisation is only going to print direct thermal, there are printers available that only have direct thermal capability. These printers are generally less costly to purchase because they do not contain any of the hardware necessary for driving and controlling ribbon. Eliminating the ribbon and ribbon hardware components also results in a less complex printer with fewer parts to wear and/or break, resulting in lower service costs and less downtime over the life of the printer.
