Greetings!
I am Alexander.
I am a PHP developer. About a week ago. I did a similar thing for a previous client. Meaning that I can adjust that source code to match the the things you need.
They required the same thing as you do ,therefore in the press of a button it generated a PDF label.
Anyways, let's talk about this. You can have this done by tommorow night.
Cheers, Alex!
