example

let Printer = require('./main')

let { esc, Image, getPixels, getPrinters } = Printer



let usbPrinter = getPrinters().find(p => {

  return p.portName === 'USB001'

})

const printer = new Printer(usbPrinter.name)

print text

esc = new esc({}, {})

esc.init().text('这里打印第一行吧？123！').flush()

printer.print(esc.buffer._buffer)

print text、barcode、qrcode（可以设置二维码大小）

esc

  .init()

  .text('test print qrcode')

  .text('测试下打印二维码')

  .align('CT')

  .barcode('1234567', 'EAN8')

  .qrimage('https://vip.com', {width: 200, height: 'auto'}, function(err){

    this.flush()

    printer.print(this.buffer._buffer)

  })

print custom image

getPixels('https://b.appsimg.com/upload/momin/2019/02/21/133/1550737570483.png', function(err, pixels) {

  this.image(new Image(pixels))

  this.flush()

  printer.print(esc.buffer._buffer)

})
