Allow mass printing of shipping labels.

We run a small business through Shopify. We have a few sales a year and orders come in very fast. We get several hundred orders within minutes and then we print our shipping labels at a later time when we are ready to ship our product. For instance, right now I need to print about 350 shipping labels. I have found that if the orders are not the same product that I cannot bulk print them using the Group function. I would simply like to be able to select a range of orders and then select print. These seems like a very basic function – Unless I am missing something I will need to print each order individually? Any input/advice much appreciated.
