pdrstore: -Creating a Printer Driver using pdr files

Description

This example demonstrates how to load -printer driver information files and create a printer driver. The purpose -of the PdrStore API is to:

Provide access to the -printer driver information contained in .pdr files for -applications to build a printer driver list
Load and create an appropriate -printer driver for a given printer.

During initialisation, the example first loads the printer driver, -then creates a session with the font and bitmap server. This is detailed in -the following sections.

Create a printer driver void CPdrExample::CreatePrinterDriver()

This function provides the following funtionality:

Opens a printer driver -information (.pdr) file using CPrinterDriver::OpenPdrL()
Gets the total number -of driver models available using CPrinterDriver::NumModels()
Creates a printer device -using CPrinterDriver::CreatePrinterDeviceL().

Display the supported typefaces void CPdrExample::DisplayTypefaces()

Gets the list of supported typefaces using CPrinterDevice::TypefaceSupport() and -displays them.

Create a printer control void CPdrExample::CreatePrinterControl()

Creates a printer control using CPrinterDevice::CreateControlL().

Preparing for printing void CPdrExample::PrintPages()

This function prepares the printer driver for printing the pages. It -involves the following:

Gets the number of bands -per page using CPrinterControl::BandsPerPage()
Gets each band to be -printed using CPrinterDevice::QueueGetBand()
Creates a graphic context -using CPrinterDevice::CreateContextL() to draw
Terminates the print -process using CPrinterControl::QueueEndPrint() when no -more bands are available.

Usage

This is a console application, so does not -have a GUI. It builds an executable called pdrstoreexample.exe in -the standard location (\epoc32\release\winscw\ <build_variant> for -CodeWarrior). The Symbian -platform build process describes how to build this application. After -launching the executable, depending on the emulator you are using, you may -need to task away from the app launcher/shell screen to view the console.
