Hello community!

Im ussing enterprise SH v16.0 I've designed my own label using ZPL code. My purpose is to use it on my delivery slip and shipping/delivery operations, showing information related to the order, like the product, quantity, destination, and other.

This is the aspect of it:

My problem is that I don't know how to create the report in Odoo to use it. 

I was trying to go trough (in developer mode on) settings => Technical => Reports, there I've created a new report called "Delivery Slip ZPL" as shown below: 

And on the QWEB Views i've pasted all my ZPL code, but it just doesn´t work

On expedition operations i can go to print => ZPL slip, it's shown there:

But I get an Error... 

The above server error caused the following client error:
RPC_ERROR: Odoo Server Error
    at makeErrorFromResponse (https://fgarcesymant-pruebaspaquetes-pruebapaquetes-9450349.dev.odoo.com/web/assets/348-69dc70a/web.assets_backend.min.js:992:163)

Does someone know how to use this kind of report using ZPL with odoo? 

First I want to be sure that I can print it, then I would do the integration with code to odoo fields... but now I need just to know how to print it.

Thanks in advance for your help, best regards,

Felipe
