191<h1>PrintFramework</h1>
192
193This is an overview of the classes and methods used to print documents.
194It also demonstrates how to do print previews and invoke the printer
195setup dialog.
196
197<p>Classes demonstrated here:<P>
198<ul>
199 <li><b>wx.Printout()</b> - This class encapsulates the functionality of printing out
200 an application document. A new class must be derived and members overridden
201 to respond to calls such as OnPrintPage and HasPage. Instances of this class
202 are passed to wx.Printer.Print() or a wx.PrintPreview object to initiate
203 printing or previewing.<P><p>
204
205 <li><b>wx.PrintData()</b> - This class holds a variety of information related to
206 printers and printer device contexts. This class is used to create a
207 wx.PrinterDC and a wx.PostScriptDC. It is also used as a data member of
208 wx.PrintDialogData and wx.PageSetupDialogData, as part of the mechanism for
209 transferring data between the print dialogs and the application.<p><p>
210
211 <li><b>wx.PrintDialog()</b> - This class represents the print and print setup
212 common dialogs. You may obtain a wx.PrinterDC device context from a
213 successfully dismissed print dialog.<p><p>
214
215 <li><b>wx.PrintPreview()</b> - Objects of this class manage the print preview
216 process. The object is passed a wx.Printout object, and the wx.PrintPreview
217 object itself is passed to a wx.PreviewFrame object. Previewing is started by
218 initializing and showing the preview frame. Unlike wxPrinter.Print, flow of
219 control returns to the application immediately after the frame is shown.<p><p>
220</ul>
221
222<p>Other classes are also demonstrated, but this is the gist of the printer interface
223framework in wxPython.
