Printing grids in ExtJS

In many ExtJS applications grids have to be correctly printed, but as ExtJS has no such functionality out of the box, you should use some third-party or your own solution. One of the best start points is to use Ext.ux.Printer plugin. It can be used not only for grids, but also other components, but you need to define custom renderer classes for your component, see article http://edspencer.net/2009/07/28/extuxprinter-printing-for-any-ext/.  After that printing from your code is very simple:

   Ext.ux.Printer.print(MyApp.components.MyGrid);
