Load a Javascript in /print

I have successfully created a print format for printing barcodes. But it uses JsBarcode (GitHub - lindell/JsBarcode: Barcode generation library written in JavaScript that works in both the browser and on Node.js). I need to be able to load this script when the print is being taken. If there is a way to include this script globally, that would be great.
