Using Print dialogs

Adding printing support to an application can be a difficult task, as there are a number of tasks that need to be handled. These include selecting and configuring a printer, translating your on-screen presentation to paper and ultimately sending the data to the printer.

In wxPython, there are three dialog classes related to printing: PageSetupDialog, PreviewFrame, and Printer. In addition to these, there are a number of supporting classes that must be used in conjunction with these dialogs in order to add printing support to an application. This recipe shows some of the basics of how to use the wxPython printing framework by creating a class that encapsulates the usage of the three printing dialogs and allows an application to print a bitmap.

How to do it…

Here are the steps to perform in this recipe:

1. First, we will make a subclass of wx.Printout. This object is used by the print framework to control how the printout is rendered to the media, as follows:
