Pricing from a PrintJobManager product engine may not show on the product page on a Pressero site if you do not have any Organizations setup in your PrintJobManager account or if the site url address of your Pressero site is not entered on the Organization's Integration ID field in PrintJobManager.
In PrintJobManager, go to the Contacts field on the left menu, select Organizations. Create an organization by clicking + Add New if none exists, or edit your existing organization by clicking the edit button to the left of your organization's name. Check the field Integration ID.
The Integration ID field needs to be the url address used by the Pressero site whose products you want to show pricing from your PrintJobManager Product Engine
