QLn Series User Guide
QLn Series Technology
The QLn420, QLn320 and QLn220 use several technologies
made popular in other Zebra Mobile Printer product lines.
Smart Battery
The QLn Series battery pack is a high capacity, smart
Lithium Ion battery that contains electronics which allow the
printer to monitor its operating parameters. Among these are
the number of charge cycles it has undergone and its date of
manufacture. Using these parameters, the printer’s software
can monitor the battery’s condition and alert the user when to
recharge or remove the battery from service.
Operating Temperature Charging Temperature Storage Temperature
-200C to +500C
The QLn Series printers will only function properly with genuine
Zebra smart battery packs.
The smart battery’s health has three states: GOOD, REPLACE, and
POOR. The battery health factor determines whether or not the printer can operate and what is communicated to the user via the display.
00C to +400C

QLn Series User Guide
Printing Technology
The QLn Series printers use the Direct Thermal method to
print human readible text, graphics and barcodes. It incorporates a sophisticated print engine for optimal printing under all
operational conditions.
Direct Thermal
Direct thermal printing uses heat to cause a chemical reaction on specially treated media. This reaction creates a dark
mark wherever a heated element on the printhead comes in
contact with the media. Since the printing elements are arranged very densely at 203 d.p.i. (dots per inch) horizontal
and 200 d.p.i. vertical, highly legible characters and graphic
elements may be created a row at a time as the media is advanced past the printhead. This technology has the advantage
of simplicity, as there is no requirement for consumable supplies such as ink or toner. However, since the media is sensitive to heat, it will gradually loose legibility over long periods
of time, especially if exposed to environments with relatively
high temperatures.

Ethernet and Charging Cradles
The cradle is an expansion base intended for use with the
QLn Series printers. There is a four bay cradle (QLn-EC4) or
a single bay option (QLn-EC) for use with the QLn220 and
320, as shown on pages 23 and 24. There is also a single bay
Ethernet and charging option for the QLn420 (QLn420-EC) as
shown on page 24.
The QLn-EC/EC4 cradles provide charging power to the
docked printer as well as providing a standard 10/100Mb/S
Ethernet port for communication to the printer. The QLn420EC also provides charging power to the docked printer, as well
as a standard 10/100Mb/T Ethernet port for
communication to the printer. All cradles also supply battery
charging power to the docked printer and acts as a supplementary power source for a functioning QLn printer.
All QLn Ethernet cradles feature two LED’s to indicate the
status of the cradle: Solid green to indicate when power is
provided to the input of the cradle; and blinking green to indicate Ethernet activity.
The cradle allows the user to dock the printer easily and remove
it with the push of a button. The printer shall remain operable while
docked, i.e. display is viewable, charge LED status is viewable, and
printer controls and data entry are available. The printer will still print
while docked and the user shall be able to replace the media as well.

Printer Operation with Cradle
• All QLn Series printers will charge when placed in their
supported cradles.
• Only QLn Series printers that have the Ethernet option installed will connect to an Ethernet network. Check the
PCC code on the back of the printer (see Appendix D
for location). Codes of the form QNX-XXXXX0XX-XX
do not support Ethernet, and codes of the form QNXXXXXXEXX-XX do support Ethernet (where “X” means
don’t care). You can also check the “Communications”
sub-menu on the LCD (see Main Menu Screen on page
17). After selecting this sub-menu, any communication
options not installed will be so indicated.
• When power is applied to the cradle and the printer is
docked, the printer charge LED indicates the charge status of the printer (see Figure 17).
• Docking the printer in the cradle will automatically turn
the printer on to ensure it is available to be managed remotely.
• When the printer detects input power from the cradle, and
the presence of a live Ethernet link, it will automatically
reboot and connect to the Ethernet network.
• For printers with an 802.11 radio, this interface will be
turned off when the Ethernet link is active. It will turn
back on if the Ethernet link is no longer active.
• For printers with a Bluetooth radio, this interface will remain active while the printer is in the cradle.
• The serial and USB ports will remain active while the printer is in the cradle.
• The DC input barrel jack connector (see Figure 12) cannot
be used while the printer is in the cradle. The DC barrel
jack should be plugged directly into the cradle insted.
