I’d like to integrate a (cheap) Bluetooth printer—like the one shown in the example image—that is typically used for receipts into my Home Assistant setup. I have a use case where I need to trigger a small printout as part of an automation.
Has anyone done something like this before? And does anyone have a recommendation for a suitable printer?
Thanks for the tip. That’s an exciting idea with MQTT and an ESP.
However, there must also be a way to connect the printer directly to HAOS and then print directly.
In order to do that, there must be an integration with the make of printer. A Bluetooth device can be ‘seen’, however as long as HA doesn’t know what it ‘does’, it won’t work.
In the video they use a mqtt to send info to the ESP, who then sends a 'print me this info ’ command to the printer.
Your best guess will be finding a printer that is compatible with CUPS, then installing the CUPS addon (GitHub - arest/cups-addon: Homeassistant Cups Addon) and adding the printer.
Once it works through the addon, you can then write a script to send a print request to the printer, see this thread for a similar question: How to make A Triggered Event automatically print to a reciept Printer on the network - #6 by PCman .
Thanks a lot!
