Is it possible to give access to the printers directly to access the generated files, if printers are 3rd party?    

In iScripts PrintLogic based sites, the user created design files will be downloaded by admin or staff from the admin control panel. This can be manually shared with third party printers if required. Please contact us if your business model is different from normal t-shirt printers, we can suggest changes in the software to automate your business without changing existing processes. Or we can make a custom modification to the iScripts PrintLogic software for you. If you are interested in a modification, send us an email to sales@iscripts.com for more information. We would be more than willing to provide you with a project quote or estimate.
