You can download multiple orders at once, should the need arise for you! On your Orders page, either use the checkmarks to the right of each order or click Other Actions at the top of your page then Select All > Export:

Click into Export in that Other Actions menu where you’ll see the options to download all selected orders, change the export format, or Mark Complete all selected orders:

When you download multiple orders like this, you’ll be creating individual excel or text documents (depending on your selected Export Format) for each individual order. You can then import them to your POS system as usual, or whatever you generally do with your order downloads.
