PayPal shipping labels with paypal api or module.

I haven't been able to find a working module for paypal labels, I need someone to recommend a module that works with proof or to quote for the construction with one using the paypal API. Paypal API and Oscommerce experience is required. The deliverable result should be my site sending the labels directly to paypal and charged on my paypal account. Set status to shipped with tracking info after label is created.
