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.

Written by the indexing model from the issue text.

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
