How do I set the orientation?

[ryan-sandy]

I'm having trouble switching the orientation from portrait to landscape.

      var printer = ipp.Printer(Config.get("printer.url"), Config.get('printer.options'));
      var msg = {
        "operation-attributes-tag": {
          "requesting-user-name": "Ryan",
          "document-format": "application/pdf",
        },
        "job-attributes-tag": {
          "orientation-requested": "landscape"
        },
        data: Buffer.from(table, 'utf8')
      };
      printer.execute("Print-Job", msg, function (err, res) {
        if (err) { console.log(err); }
        console.log(res);
      });

I am super new to this so any help would be appreciated. Thanks in advance!
