Wearable Wired Printers

It may be more convenient or necessary for individual workers to be able to print from their

location for the purposes of affixing labels as part of their work operations.

Wearable wired printers, such as the QL series from Zebra™ Systems, can be an ideal choice

for this type of operation. These printers typically offer various interface modes including

RS-232, WLAN or Bluetooth. (Note that Bluetooth printing is not supported on the T2 Series

devices.)

WLAN via an Output Data Record (ODR) – A Vocollect task loaded on the T5 Series or T2

Series devices can send output to an ODR that is associated with a specific printer. A table

of printers and their associated TCP/IP (network) addresses or names can be built into the

task. The operator may simply voice select the desired printer at the beginning of a shift to

associate a particular mobile printer with their terminal for the duration of the shift.

WLAN via a server system – Similar to a stationary printer, the T5 Series or T2 Series

devices may be able to make a request to a central server system to initiate printing to a

specific mobile printer via voice selection. The ability to do this depends on the type of server

software being used in conjunction with the T5 Series or T2 Series devices and also may

require more system management support to tend to multiple output queues.

RS-232 interfaced printers – These printers are appropriate only for printing small amounts

of data. T5 Series and T2 Series devices do not support the hardware or software flow

control needed to moderate a large data transfer at high speed. Using these printers

requires that the operator be tethered to the printer with a cable.

Wireless Bluetooth printers are also available. These are discussed later in this document.

Troubleshooting Wearable Wired Printers

Issues with wired printers can be:

 Battery wear – just like all mobile devices printer batteries are subject to wear. If a

mobile printer does not function, a good first step is to assure that its battery is in

charged.

 Cord deterioration - repeated bending, pulling and stretching of the cord via normal

wear and tear can cause it to fail. If a wired wearable printer is not printing, testing

it with a cord that is known to be good may resolve the issue.

 Paper or ribbon issues – it’s important to have supplies on-hand so that workers can

quickly have them replenished.
