Hello @januslo I couldn't find any way to print bold text on my printer,SO how could I print bold Text on printer.

Thank you.

you may need to check the ESC/POS command to figure out the "bold command" then send the raw data (bytes )with sendRAWData () method. Or yo u may call setFontSize() before call printString set make font larger
