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:
{@sample Core/PrintDocument Example}
constructor(options?: any): PrintDocument

Gets or sets a value that determines whether the PrintDocument should include the CSS style sheets defined in the main document.
The default value for the property is **true**.
Gets or sets the document title.
The default value for this property is **null**, which causes the PrintDocument to use the title from the current document's **title** tag.
addCSS(href: string): void
Adds a CSS style sheet to the document.
URL of the CSS file that should be added to the document.
append(content: string | Element): void
Appends an HTML string or an element to the document.
