Mastering GUI Programming with Python

Configuring the printer

Printing begins with a QtPrintSupport.QPrinter object, which represents a printed document in memory. The basic workflow of printing in PyQt is as follows:

1. Create a QPrinter object
2. Configure the QPrinter object using its methods or printer configuration dialogs
3. Print QTextDocument to the QPrinter object
4. Pass the QPrinter object to the operating system's print dialog, from which the user can print using a physical printer

In MainWindow.__init__(), let's create our QPrinter object, as follows:

        self.printer = qtps.QPrinter()        self.printer.setOrientation(qtps.QPrinter.Portrait)        self.printer.setPageSize(qtg.QPageSize(qtg.QPageSize.Letter))

Once the printer is created, we can configure a wide number of properties; here, ...
