Mycroft skill to support output on receipt thermo printer.
Only tested with a cheap thermo receipt printer that has 'PT-210' as the only marking on the device...
In theory this should work with every printer that is connected via USB and accepts plaintext (ESC/POS) commands.
This skill will only work on a custom mycroft instance such as picroft on a Raspberry Pi.
Before the skill can be used, the user who runs picroft has to be added to the 'lp' (line printer) system group.
Example that works in most cases.
sudo addgroup pi lp
Now, attach the printer to the USB port.
In the ideal case, the printer shows under /dev/usb/lp0.
$ file /dev/usb/lp0
/dev/usb/lp0: character special (180/0)
Add this path to the 'local path' setting on the Mycroft skills config page.
In some rare cases, it might be required to add a new udev role to the system.
Please consult the internet about this...
Access the skill settings via Mycroft Skills page.
