<h1>PrintFramework</h1>

This is an overview of the classes and methods used to print documents.
It also demonstrates how to do print previews and invoke the printer
setup dialog.

<p>Classes demonstrated here:<P>
<ul>
    <li><b>wx.Printout()</b> - This class encapsulates the functionality of printing out
        an application document. A new class must be derived and members overridden
        to respond to calls such as OnPrintPage and HasPage. Instances of this class
        are passed to wx.Printer.Print() or a wx.PrintPreview object to initiate
        printing or previewing.<P><p>

    <li><b>wx.PrintData()</b> - This class holds a variety of information related to
        printers and printer device contexts. This class is used to create a
        wx.PrinterDC and a wx.PostScriptDC. It is also used as a data member of
        wx.PrintDialogData and wx.PageSetupDialogData, as part of the mechanism for
        transferring data between the print dialogs and the application.<p><p>

    <li><b>wx.PrintDialog()</b> - This class represents the print and print setup
        common dialogs. You may obtain a wx.PrinterDC device context from a
        successfully dismissed print dialog.<p><p>

    <li><b>wx.PrintPreview()</b> - Objects of this class manage the print preview
        process. The object is passed a wx.Printout object, and the wx.PrintPreview
        object itself is passed to a wx.PreviewFrame object. Previewing is started by
        initializing and showing the preview frame. Unlike wxPrinter.Print, flow of
        control returns to the application immediately after the frame is shown.<p><p>
</ul>

<p>Other classes are also demonstrated, but this is the gist of the printer interface
framework in wxPython.
