I'm trying to answer a question that's stumped a few people. I currently have an OSCommerce site (not an osCmax site yet), we're a drop-shipping company and have a multiple vendor system. The issue is this;

I want to be able for my vendors, who log in to a "Vendor" section on the beck end of our site to see only their orders (this part is already taken care of), to be able to print UPS shipping labels and my sites packing slips by pressing a "Print" button or something similar built into the page. I've found solutions that work for a single vendor, but nothing that is built specifically for multiple vendors.

Has anyone set up a system like this and got it working? Or know of a site that works this way? Or know of a bundle that does this? Or anything at all?

If it means switching to OsCmax or any other sort of bundle, please, I'm all ears. We've been working on this for the better part of 3 months with no luck so any help at all would be appreciated.
