Printing PDFs with IPP

Using the IPP package to print PDFs.

var ipp = require("ipp"),
    PDFDocument = require("pdfkit");

var doc = new PDFDocument({margin:0});
doc.fontSize(24);
doc.text("Hello World", {align: 'center'});

// Use your printer URL here. It must support IPP
var printURL = "http://localhost:631/printers/Lanier_MP_3500";
var printer = ipp.Printer(printURL);
var buffers = [];
doc.on('data', buffers.push.bind(buffers));
doc.on('end', function () {
  var file = {
    "operation-attributes-tag":{
      "requesting-user-name": "User",
      "job-name": "Print Job",
      "document-format": "application/pdf"
    },
    data: Buffer.concat(buffers)
  };

  printer.execute("Print-Job", file, function (err, res) {
    console.log("Printed: "+res.statusCode);
  });
});

doc.end();
