This tool allows you to setup the WiFi on a wireless Xprinter thermal receipt printer on Linux, without the use of the official Windows-only setup tool.
To use it, plug your thermal printer into a USB port and determine
it’s device file. For example /dev/usb/lp0. From there you just
have to run ruby xprinter-wifi.rb /dev/usb/lp0 and it should
prompt you for the values required.
This script was created as part of a blog post about reverse engineering thermal printer setup commands.
