You can print images, but they need to be 384px wide.
It's a fluent API, so you can chain functions, but don't forget to call print at the end to actually print something!
You'll need an USB/Serial converter.
- install with
npm install thermalprinter --save - check the demo sample:
var SerialPort = require('serialport').SerialPort,
serialPort = new SerialPort('/dev/ttyUSB0', {
baudrate: 19200
}),
Printer = require('thermalprinter');
var path = __dirname + '/images/nodebot.png';
serialPort.on('open',function() {
var printer = new Printer(serialPort);
printer.on('ready', function() {
printer
.indent(10)
.horizontalLine(16)
.bold(true)
.indent(10)
.printLine('first line')
.bold(false)
.inverse(true)
.big(true)
.right()
.printLine('second line')
.printImage(path)
.print(function() {
console.log('done');
process.exit();
});
});
});
