Ubuntu :: Print From Folder Automatically?

I need to setup a network scanner which will scan to a folder via the network onto an Ubuntu pc. When the file is scanned I need the Ubuntu pc to automatically print the file to the default printer and then deletes the scanned file.

I haven't been using Ubuntu very long and was not sure how to achieve this. I was wondering if perhaps I should write a script, after learning how to, that checks the folder for any files and then prints them. Once printed it then deletes the files. Would I need to have this script running via a scheduler that runs the script every second? Or is there another way to achieve this?
