Print image using DataURL

[aabanaag]

Hi, I have a question if printing an image using dataURL will be possible? Also any updates on sending the print via buffer? It is possible to utilize async/await from ES6?

@aabanaag this works for me in electron

let imageData = canvas.toDataURL('image/jpeg')
let base64Data = imageData.replace(/^data:image\/\w+;base64,/, '')
let dataBuffer = Buffer.from(base64Data, 'base64')

printer.printDirect({
      data: buffer,
      type: 'JPEG',
      printer: this.printer, 
      success: function (jobID) {
        console.log('sent to printer with ID: ' + jobID)
      },
      error: function (err) {
        console.log(err)
      }
})
