I've installed the PDF Invoice contribution of osCommerce and had no problems with it.
However, to save time, if we have several orders it would be good to print all of these at the same time.
Is there a way to alter the code to generate the invoices on separate pages when the order status is set to 2 (picking and packing)
to save posting all of the code here, i'm using this contribution: [addons.oscommerce.com
...] version: PDF Invoice V1.4
