Can i hook 2 iPads up to the same chipless card reader and cash drawer/printer?

[Kellyf99]

Bought a second iPad and not sure how or if i can use them on the same cash drawer/printer and contactless chip reader

you can use the same cash drawer and printer IF it is an ethernet printer, not one that is attached directly to the iPad via USB.  The chip reader can only be paired to one device at a time.
