PrintDocument (Angular)

The PrintDocument class lets you create and print documents.

You can add content using the PrintDocument.append method and print the document using the PrintDocument.print method.

This sample prints the radial gauges and the Grid as a table (spanning multiple pages).

This example uses Angular.
