Hardline the Wireshark system to that port and record the traffic that way. On your wireless router/switch setup port mirroring to a specific port on the device. I don't know if Android has this capability or not. Receive notifications of new posts by email. Setting the traffic ROUTE on your phone to tunnel through your system that is running Wireshark. ChallengeĬan you manage to extract the printed pages out of this trace? D ) Filter for the iPhone’s MAC address in the trace to find all appropriate packets: “eth.addr = d4:a3:3d:97:60:6d”: Printing via AirPrint: Overview.įiltering for “ipp” shows only some HTTP-like lines, while there are much more packets involved in the “tcp.port eq 631” flows: Printing via AirPrint: IPP. Hard to troubleshoot, but working without any configuration. My printing of a single page took about 10 TCP/UDP streams and roughly 1200 packets. In my case, the iPhone found the printer via some MDNS discoveries that are shown in the trace as well. Android PCAP implements the Linux kernel RTL8187 driver in userspace using the Android USB host API. Press question mark to learn the rest of the keyboard shortcuts. AirPrintĪpple’s AirPrint uses the Internet Printing Protocol IPP on TCP port 631 (I have never heard of it). but something thatll work as a network analyzer get vlan, dhcp from an ethernet connection. It seems like the mere print data is encoded in the same way as the Raw variant: Printing via LPD/LPR TCP port 515. Wireshark’s display filter is “lpd” while you can find the whole stream with “tcp.port eq 515” or the like. The Line Printer Daemon protocol/Line Printer Remote protocol (or LPD, LPR) uses TCP port 515. You’ll find it via “tcp.port eq 9100”: Printing via Raw TCP 9100. Wireshark has no protocol dissector for this raw printing (little discussion here). It is also called HP Jetdirect, or the like.
