Hi, 

In odoo, you can print picking barcode. This mecanism is based on the name of the picking that is sent to controller /web/report/.. and returns a png. 
However, i would like to get the serial number (123456789012..) of the generated barcode because i need to print it in zebra label. is there a way to do so ? 

I think about adding a new field barcode to picking and generate one barcode on my own. but that would also mean i need to change the report to consider it instead of the name of the picking. Also, i ignore if there are other things that must be changed too.. 

Regards.
