This document contains various notes relating to the Zebra QL 320Plus mobile printer, often used for product labels.

== ZPL II ==

The QL 320Plus uses the [[https://km.zebra.com/kb/index?page=content&id=SO6753&actp=LIST_POPULAR|CPCL]] language by default, but also allows for [[https://km.zebra.com/kb/index?page=content&id=SO6755|ZPL II]] (as well as [[https://km.zebra.com/kb/index?page=content&id=SO6632&actp=LIST|EPL2]]) emulation.  However, getting it to "play nicely" may take some tweaking of printer settings initially.

{{{#!wiki note
Instructions on how to send command sequences to the printer are documented [[http://www.zebra.com/us/en/support-downloads/mobile/ql-320-plus.html#mainpartabscontainer=manuals|elsewhere]] and will not be covered here.

=== Emulation ===

The first step in my testing was to configure the printer's emulation to use ZPL II ''instead of'' EPL2 (etc.).  This involved sending the following CPCL command to the printer:

{{{
! U1 setvar "device.languages" "ZPL"
}}}

=== Calibration ===

According to this [[https://km.zebra.com/kb/index?page=content&id=SO8313&actp=LIST|knowledge base article]]:

 If using ZPL emulation, the printer needs to be calibrated before it will recognize label lengths within ZPL.

The article further references a [[https://support.zebra.com/cpws/docs/comtec/mobile_printer_calibration.htm|calibration document]] with some more specifics.  The step required in my testing was to send a ZPL command sequence to the printer which basically instructs it to calibrate itself:
