We're running into issues at some of our locations with our mobile apps on our Zebra TC20 devices being able to discover our Zebra Q620 mobile printers via the Zebra discovery package. They both connect and communicate via wifi. Our network team has requested technical information on how that package works to discover the mobile printers so they can ensure our network at those locations is configured correctly to accommodate how that package works. Can a technical resource please describe the technical details on how that package discovers the mobile printers? Protocol, ports, etc. needed from a network side
