Hello everyone,

I want to be able to print 3 different sizes of product label when i press the "print label" button. In the menu there are already options (2x7 pdf, ZPL etc.) but I want to customize so I can choose the different 3 sizes and customize the print via zpl. I am using a GK420D Zebtra printer. 

Ive tried making a module and also tried modifying the qwebs but with no luck. I might have missed something for this to work, but I cant figure it out.

So what is the best way to do this? app?
