# Wijmo.Printdocument ## Content

PrintDocument Class

Class that enables the creation of custom documents for printing.

The PrintDocument class makes it easy to create documents for printing or exporting to PDF. Most browsers allow you to select the paper size, orientation, margins, and whether to include page headers and footers.

To use, instantiate a PrintDocument, add content using the append method, and finish by calling the print method.

For example:

import { PrintDocument } from '@mescius/wijmo';

// create the document
var doc = new PrintDocument({
  title: 'PrintDocument Test'
});

// add some simple text
doc.append('<h1>Printing Example</h1>');
doc.append('<p>This document was created using the <b>PrintDocument</b> class.</p>');

// add some existing elements
doc.append(document.getElementById('gaugeControl'));

// print the document (or export it to PDF)
doc.print();

The example below shows how you can create a printer-friendly version of a document which can be printed or exported to PDF and other formats directly from the browser:
