I'm looking to set up a workflow for a photo gig coming up. Here's what I would like to do: Take a photo with a camera (Canon 6D) wirelessly tethered to a MacBook Pro (using Kuuvik Capture). Have a watch folder service using Automator on the session folder where the photos are being imported automatically. There will be three printers (Canon PIXMA MG8220) connected. Route the new image that was imported to the next available printer. Each print takes about 20–30 seconds, so ideally I'd like Automator to look at the print queue, then if the queue is empty, print the photo. If it's not, check the queue length of the others and put the photo into the next shortest queue. Is there an easy way of doing this? There will be an assistant, however, they would be doing other things and likely wouldn't be able to manually route the prints. Before jumping in and programming this all manually, I'd like to see if there's a simpler way first. Any help would be greatly appreciated!
