Happy Monday!!! We have a client that sells a lot of items that require a PDF printed for each item on the sales order. And then those printed docs have to be added to the shipping box/container. I have made a custom field on the item that holds the required PDF doc. And made a custom column on the transaction line that is sourced from the item. Is there a way to add each of those required documents to a print queue? I think they would prefer it to be printed when they print the packing slips. =]

You can but there will be scripting involved. You can add a button that will call a suitelet which will print your required docs.

@tuli Hey! Thanks for the response. I should've mentioned it, but this is something we have thought of and kind of our backup plan. The problem is, they're going to have to manually click on each sales order to print those required docs. This is fine, but I would like to try and do it when doing bulk fulfilling/printing. If that makes sense!
