This is the simplest use of this library. Basically, import the library port-thermal-printer, and execute the method this.printDirect();, giving the port and the text do you want to print as parameter. If the port or text given are empty, the printDirect will throws an Param required exception.

const portPrinter = require('port-thermal-printer');

    portPrinter.printDirect(port, text); 
} catch (err) {
    console.log(err.message);
