How can I modify Item Fulfillment Label

AI generated answer (using internal Slack threads):

To modify the Item Fulfillment Label, you would need to create a custom Suitelet that opens a pop-up. You can submit data which is added to the fulfillment, and prints a label, which is rendered in the script. However, duplicating the integrated shipping label might not be possible. If you're trying to grab the label and email it via a workflow, you might face some challenges. One possible solution could be to create a script that saves the label ZPL to NetSuite documents, and then attach it to that transaction. After that, you could email it with the Purchase Order. To check if the packing slip or integrated shipping label was printed on an item fulfillment, you could create a workflow/script that checkmarks a box once the user hits the print label button. However, if the user prints via the UI record, it does get removed from the mass print list which means some field is being changed. Unfortunately, it's not clear if that field is exposed. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
