I use WooCommerce with ShipStation to sell t-shirts.
I cannot figure out a way to print the sizes on the shipping labels. ShipStation has an option to print "product name" or "sku" on the shipping labels. This makes it extremely easy to print out all my labels, and then package them with the correct products by simply reading the label.
The problem is, it does not print the product sizes (attributes).
Is there a way to do this?
