@sami.janati It depends on the method of connection you are using for your printer. The Edge IO has many type of connection ports as detailed in the spec link above - so as long as there is another port to hook up to, you should be good to go to hook it up to multiple devices!
Another consideration is that depending on the device, you can connect it to Tulip multiple ways, (for example Zebra printers (Update Tulip Device Library Printers Page - #4 by k.ober) so there are also options there
