Print customs declaration at packing station?

I often send packages via DHL Packstation and always print the shipping label there since I don't have a printer at home. I recently franked a package online with DHL and received the QR code to print my label at the Packstation. I also had to fill out a customs declaration (since the package is being shipped to the USA).

Will the Packstation print just the label or also the customs declaration? Since both have a common QR code.

Thanks
