+>> Printing Section
+
+This section holds configuration directives related to printing. It is delimited by the `![printing]`! header in the configuration file. Available directives, along with example values, are as follows:
+
+>>>
+`!print_messages = no`!
+>>>>
+Determines whether messages should be printed upon arrival. Must be a boolean value, and is turned off by default.
+<
+
+>>>
+`!message_template = ~/.nomadnetwork/print_template_msg.txt`!
+>>>>
+Determines where the template for printed messages is found. Must be a filesystem path. If you set this path to a non-existing file, an example will be generated in the specified location.
+<
+
+>>>
+`!print_from = 76fe5751a56067d1e84eef3e88eab85b, trusted`!
+>>>>
+Determines from which destinations messages are printed. Can be a list of destinations hashes, the keyword "trusted", or "everywhere".
+<
+
+>>>
+`!print_command = lp -d PRINTER_NAME -o cpi=16 -o lpi=8`!
+>>>>
+Specifies the command that Nomad Network uses to print the message. Defaults to "lp". The above example works well for small thermal-roll printers.

 >Ignoring Destinations
 
 If you encounter peers or nodes on the network, that you would rather not see in your client, you can add them to the `!~/.nomadnetwork/ignored`! file. To ignore nodes or peers, add one 32-character hexadecimal destination hash per line to the file. To unignore one again, simply remove the corresponding entry from the file and restart Nomad Network.
