Section 1: QL Introduction

Description

The Zebra QL220, QL 220 Plus; QL320, QL 320 Plus; QL420 and QL 420 Plus Mobile Printer s are low-cost, portable, direct thermal printers. They can be carried by the shoulder strap, sit on a work space, or be mounted to a specific location. They are powered by a Li-Ion battery pack which makes them particularly useful in environments where AC power is not readily available. The QL series of printers delivers traditional Zebra reliability in a transportable label printer for the mobile work environment.

Operating Modes

•Tear-Off Mode. The operator tears off a single label (or a strip of labels) after printing.

•Peel-Off Mode. The liner is peeled away from the label as it prints, the printer waits until the operator removes the label, and then the next label prints.

Printing Technology

The QL series printers utilize direct thermal printing wherein a substrate, typically pa- per, is coated with a chemical that changes to a dark color upon exposure to heat over a period of time to form an image.

Communications

Communications between QL series printers and a host terminal can occur in four basic ways:

•By a cable between the printer and its host terminal using either RS-232C or USB 2.0 communication protocols.

•Linking to a host terminal via Infrared (usually by means of the industry standard IrDA protocol)

•By means of a Bluetooth® short range radio frequency link.

•By means of a wireless LAN (Local Area Network) per 802.11 specifications.
