Print using CUPS

Two things, I asked you to

    1. Add a catch node connected to a debug node (set to display the complete msg object)
    1. run NR from the command line and look at the log after you try to print then copy and paste the log in a reply

In addition, please don't do screen prints, copy the debug information and paste it to a reply.

There’s a great page in the docs (Working with messages : Node-RED) that will explain how to use the debug panel to find the right path to any data item.

Pay particular attention to the part about the buttons that appear under your mouse pointer when you over hover a debug message property in the sidebar.

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```)
