Delaney & Co. Mailers review for Shopify Order Printer

I do not like the new app at all. My old template doesn't work and I can't seem to edit this one with any of the coding. Someone please tell me how to get the shipping title to show on the packing slip? It takes too much time to look at each order individually to see what shipping method to use. I tried several of the variables and none of them are working!
