At first I would say it's not compatible. Loyverse POS for iOS is a little bit limited regarding bluetooth printers. You can only use those from the recommended printer list, which would be the Star TSP654IIBl (Bluetooth) and the Star mPOP.
About your mobile printer, if you already own it, you could actually try to set it up, using the TSP654IIBl (Bluetooth) as printer model in the printer settings.
Who knows, it could work, but the chances are not high. Hey, if you have results let us all know about it, whether it worked or not, it would be good for everybody to know.
