Generate a PDF packing slip and a PNG shipping label from the same order data. First, use generate_document with format "pdf" to create a packing slip with order number, shipping address, and itemized contents. Then, use generate_image to create a 4x6 inch shipping label with sender address, recipient address, barcode with [tracking number], and shipping method.
