I have been looking for ESC command extension. The one used for Printing via Bluetooth. I would like to make this extension for educational purposes. But unfortunately, I can only trace a PAID extension. I’ve been trying to reach out to the extension developer but there’s no response. Is there a better way I can acquire that extension? or contact the extension developer?
1 - We assist in all cases where there is a solution. But have you asked yourself: but, if there is no any extension like this at the moment?
2 - It is not a good practice tagging someone just to get your answer fast. That’s why we are a community. Maybe there is another user who has the solution… or maybe not. But don’t do this again, please!!
You will find at the end of the post a link to the developer’s blog, in the blog is his email address.
Send him and email and check if his still arround so you can buy the extension.
You don’t need extension for printing simple text in ESP/POS printer. Use Bluetooth Client component from Kodular. Very easy and simple, just call method send text.
If you want text formatting or barcode, etc. Read ESC/POS manual and find what is the command for that. Then use send byte methods in Bluetooth Client component to send the command.
For example (underline text)
send1ByteNumber 27,
send1ByteNumber 45,
send1ByteNumber 1,
sendText, “Helooo”
