+# Networks of ZPL Printers
+
+ZPL supports several networking methodologies
+
+## Ethernet
+
+### Config
+
+> EPL doesn't appear to have a way to directly configure network settings, the manuals only reference SGD commands.
+
+ZPL has several commands to set network settings, they act slightly differently depending on firmware version and hardware config.
+
+* The `^NS` command appears to be oldest, with the first 4 parameters (a,b,c,d) seemingly being universal.
+* As early as 2006 the "Wireless and Wireless Plus print servers" added parameters to the NS command, up to `^NSa,b,c,d,e,f,g,h,i`.
+* The separate `^WI` command was added for configuring wireless network settings, see the wifi section below.
+* Later firmware versions added the `^ND` command, which can set external wired, internal wired, or wireless settings using the same command. It'll work as an alias for `^NS` or `^ND` depending on the `a` parameter.
+
+Example to set a static IP of `192.168.1.151`:
+
+`^NSP,192.168.1.151,255.255.255.0,192.168.1.1`
+
+The default IP resolution mode is `all`.
+
+### ZebraNet PrintServer II
+
+For a while Zebra offered an external ZebraNet PrintServer II device that plugged directly into the parallel port on most printers. On some models they also offered this as an embedded option, either as a module or directly on the same circuit board in the case of some LP-2844 series.
+
+Newer models offer a more integrated networking stack.
+
+Different features are supported depending on generation, though the ZebraNet PrintServer II era tend to be very similar.
+
+Ports:
+
+* 21 - FTP
+* 23 - Telnet
+* 80 - HTTP web server
+* 161 - SNMP
+* 162 - SNMP Trap on ZebraNet Alert
+* 515 - Printer port (Line Printer Daemon)
+* 631 - IPP (Limited models)
+* 4201 - (UDP) Zebra network auto-discovery port
+* 9100 - Raw network printing
+* 20035 - (UDP) WCSO wireless auto-discovery port
+
+ZebraNet may negotiate some dynamic ports too.
+
+### LinkOS Printers
+
+These are more complex and add additional ports in addition to the above. They can also be configured.
+
+* 443 - HTTPS web GUI
+* 9143, 9243 - TLSRAW connections
+
+### Discovery Protocol
+
+This section is copy/pasted [from JFR's blog post here](https://jfr.im/blog/2024/09/zebra-network-discovery-protocol/).
+
+> Discovery client sends a UDP packet to port 4201 (unicast or broadcast), containing the data: `0x2e2c3a010000`, or `.,:\x01\x00\x00`.
+>
+> Actually, the discovery client sends 3 identical such packets (from the same socket), then waits 1 second, then repeats the process from a new source port. It sends 3 packets 3 times, for a total of 9 packets. This appears to be meant to handle UDP’s lack of reliability; the printers reply to each packet (for a total of 9 replies from each printer).
+>
+> The printers reply back with a (now unicast) packet beginning with `0x3a2c2e` or `:,.`. This is followed by a 0x03 byte, I’m not sure if this is part of the magic bytes or part of the data, and then the data begins with the “Product Number”.
+>
+> This set of information is displayed verbatim in the ZebraNet Bridge tool:

+
+## Wifi
+
+I don't have a machine with wifi! These include lots of fun commands.
+
+## Bluetooth Serial
+
+I don't have an older style bluetooth machine!
+
+## Bluetooth LE
+
+Modern LinkOS devices tend to support Bluetooth LE, especially if they have a tap-to-connect NFC tag.
+
+## RS-485
+
+WebZLP does not currently implement RS-485 networking. Ask if you need this, I would very much like to know more about why!
+
+Some models of printers are designed to be connected on an RS-485 serial bus network. When connected to such a network each printer has a _Network ID_ that controls how to talk to a given printer. Each network ID is 3 digits, 000 through 999.
+
+Several commands are used for controlling serial networks:
+
+* `~NC` - Network Connect, used at the start of the label to wake up the printer and send subsequent commands.
+* `^NI` - Assign network ID number to a given printer.
+* `~NR` - Set all network printers "transparent" (disconnect)
+* `~NT` - Set current printer "transparent" (disconnect)
