I believe if you added an action (possibly through Workflow) to the screen which did what you wanted it to do, you could create an Import Scenario subscriber which would click the action.

What I’m not sure about is if you can use Workflow to print to DeviceHub, but it seems like you could.

Were you able to create an action that would print through Devicehub?  I have a need to print a form (Shipment Confirmation) from a business event.  We started with adding a Shipment filter to the Process Shipments screen, but now I’m finding that business events and Process screens don’t play well together (no matter what screen I point to, no matter what action, I get the error “The table with the name ‘xxFilter’ does not exist in the database” where “xx” is the primary table name of the process screen, such as SOShipment).
