A printer device context is specific to Windows, and allows access to any printer with a Windows driver. See wxDC for further information on device contexts, and wxDC::GetSize for advice on achieving the correct scaling for the page.
wxDC, Printing framework overview
wxPrinterDC(const wxPrintData& printData)
Pass a wxPrintData object with information necessary for setting up a suitable printer device context. This is the recommended way to construct a wxPrinterDC.
wxPrinterDC(const wxString& driver, const wxString& device, const wxString& output, const bool interactive = true, int orientation = wxPORTRAIT)
Constructor. With empty strings for the first three arguments, the default printer dialog is displayed. device indicates the type of printer and output is an optional file for printing to. The driver parameter is currently unused. Use the Ok member to test whether the constructor was successful in creating a usable device context.
This constructor is deprecated and retained only for backward compatibility.
