Hey @RachelleE
If you're using a USB Printer, you can only plug the printer into one device, either 1 Regsiter or 1 Stand, (without doing some type of more intense work-around setup with cable splitters and things, if that would even work).
If you're using a WiFi Printer, you can hook up it up to as many devices as you'd like.
Hope this helps, and let me know if you have any other questions!
Pesso
