First things first, the device looks something like this so you don't have to assume for which device this guide is for:

This device was manufactured by Edimax in the 90s and it just so happens to work well with even ancient printers like the HP 5L. The real device's name is: PrintSir 1P/9E and it has a unique PS-something name. Do not google that as it unique per each unit (I think).

As this device is old I am assuming you found it either on Ebay, Flea Market or the local dump and want to make use of it. This is quite a problem because those can be password locked. Thankfully mine wasn't but it had some network settings I had to get rid of.

However this might not be your case and I'll list how you'd use it depending on what network settings the last owner left it on.

This guide will include a step-by-step guide on how to set up an board running Armbian to act as a gadget device (similar to how it's been advertized with the Pi Zero)

Prerequisites

You will need a:

• Armbian supported board with an OTG port
• A temporary spare monitor, USB keyboard and display cable (or serial, if you'd like that instead)
