Order Printer

I installed this app, because it's a requirement to use with the Orderly Packing Slips. The packing slips are beautiful, a much needed upgrade to the Shopify packing slips. HOWEVER - you can't print the packing slips from the same page that you fulfill the order. So you have to 1) fulfill the order, 2) exit out of the order itself back to your Shopify Orders page, 3) select the checkbox next to the order and click "Print with Order App," 4) be taken to the Order App page, THEN you can print the dashboard. For one or two orders, it's annoying but not a huge deal. But if you're fulfilling a lot of orders at one time, it's a hassle to have to fulfill the orders on one page, then go somewhere else just to print the packing slips.

This app has several drawbacks. 1. It lists the customer information at the bottom rather than at the top of the order. 2. It doesn't right justify the item cost. 3. It doesn't show the actual cost if more than one item is ordered.
4. It doesn't show the price before the discount.
5. It doesn't show an automatic discount at all.
6. It doesn't work with Draft orders. Some of these issues can be changed by editing, but why isn't this designed to write a clear customer invoice?

注文の商品点数が変わった時に、明細に最終的な数量が反映できませんでした。 Liquid変数を比べてみたところ、
注文管理＞明細書を印刷する で出力する明細書は {% for line_item in line_items_in_shipment %} が使えますが、
Order Printerだと {% for line_item in line_items%}しか使えません。 これが原因かと思うのですが、どちらも同じ変数が使えるようになりませんか？
