We are building a web app for an inventory management/order fulfillment system that processes 1500-2000 orders per day. The order fulfiller scans items that he is packing into a shipment until all items have been packed. At that time, the fulfiller clicks "Finish", and we need to automatically print all of the associated shipping labels and packing slips. Further, the shipping labels need to be routed to the label printer and the packing slip to another laser printer.
We've completed the integration with the carrier to retrieve an image of the shipping label, and we've styled the confirmation page so that prints as a packing slip. Any ideas on how to automatically print upon completion of the order? I know that we can't do this in HTML/JS for security reasons...so what alternatives are there? Applet? ActiveX control? Any other suggestions?
