Hi DantSu, first of all thank you for this wonderful free library. We currently have the library implemented in our Android APP, it works without problems, we have tested it on numerous printers and it works perfectly. However, it doesn't work on any innerprint.

Thanks for your help

Your inner printer seems to not be compatible with standard ESC POS commands. On some printer ESC POS commands have to be enabled with an external button or a parameter in the printer settings.

Thank you for your prompt response, but I think the printer is compatible with ESC/POS because it works with other printing APPs without problems:

It's not compatible with all ESC POS commands.

thank you very much, effectively commented the line this.printerConnection.write(textColor); the "r" is deleted. Also the version of the library was not updated to 3.2.0 WhatsApp Image 2022-06-10 at 4 28 45 PM
