To avoid you playing favorites, can you provide a specific list of apps that supports adding Barcodes (specifically, Barcode 128b) to an existing Packing Slip Template for purposes of printing a scannable barcode using Quickbooks Desktop Enterprise.

As I mentioned before, I could not find the app(s) referred by one of the moderators.  Your providing an unbiased listing of apps that will do the job will be of great help.  Thanks!
