If it doesn’t show up there then you won’t be able to access it via the ImageCapture framework. You should talk with your printer vendor to see if they have driver software that integrates with Image Capture. If not, you’ll need to pursue other approaches:
Perhaps the printer vendor has an SDK for talking to its scanner component?
Or they have an app you can script?
Or they document the on-the-wire protocol it uses?
Share and Enjoy
