Description
I am using the following command to print text but its not doing so, just printing the barcode
printer
.font('a')
.align('ct')
.size(1, 1)
.text('EAN13 barcode example')
.barcode('123456789012', 'EAN13') // code length 12
.cut()
.close();
I am not sure which printer it is, because it is white labelled with a private company's name, but in the command it is mentioned
ESC/POS/TSC/EPL/CPCL
It would be really helpful if your example may include full code to design a barcode, with different kind of placements

Research direction
No source file or test is named. Start by reproducing the shown printer.font, align, size, text, barcode, cut, and close sequence, then determine which of the listed ESC/POS, TSC, EPL, or CPCL protocols the white-label printer uses; done means text prints alongside the EAN13 barcode and the behavior is documented with a complete placement example.
