76mm width printing area. 80mm - 2mm of marging on each side.
203dpi
48 chars per line

This seems to solve the issue, but in this repo i dont see any option for setting this.

Also setting encoding is not avaiable but getiing encoding is available !

Of course you can do:

ThermalPrinter.printFormattedText({
    // ... your settings ...
    printerDpi: 203,
    printerWidthMM: 76,
    printerNbrCharactersPerLine: 48
}, function() {
    console.log('Successfully printed!');
}, function(error) {
    console.error('Printing error', error);
});

As you can see here:

If you specify the charsetEncoding in the JSON object you can also specify a charsetName and/or charsetId.
Example:

ThermalPrinter.printFormattedText({
    // ... your settings ...
    charsetEncoding: {
        charsetName: 'windows-1252',
        charsetId: 16
    }
}, function() {
    console.log('Successfully printed!');
}, function(error) {
    console.error('Printing error', error);
});
