Before we write our first printing application, it's important to understand how printing works in Windows and what role GDI+ plays in the process GDI+ is an application-level library that allows applications to interact with display devices such as monitors, printers, and scanners through the device drivers Figure 111 illustrates the role of GDI+ in the drawing process The application passes data to GDI+ GDI+ is responsible for converting the data into graphics format (pixels) with the help of display drivers and sending it to the display driver, which displays the data on a device such as a monitor

The printing process, which is very similar to the drawing process, is shown in Figure 112 The application sends data to GDI+, which communicates with a printer driver that sends data to the printer

The drawing process involves a surface, which is the container for graphics shapes In Windows applications, a form works as a drawing surface In previous chapters we used the Graphics object associated with a form to access the surface associated with a form There are several ways to get the Graphics object associated with a form The simplest way is to use the form's paint event handler and

PaintEventArgsGraphics property, which returns theGraphics object for the form to which this paint event handler belongs Another way is to use the CreateGraphics method Listing 111 uses PaintEventArgsGraphics to get the Graphics object associated with a form Once you have the drawing surface (Graphics object), you can use draw and fill methods

private void Form1_Paint(object sender, SystemWindowsFormsPaintEventArgs e) { Graphics g = eGraphics; SolidBrush redBrush = new SolidBrush(ColorRed); Rectangle rect = new Rectangle(150, 80, 200, 140); gFillPie(greenBrush, 40, 20, 200, 40, 00f, 600f ); gFillRectangle(blueBrush, rect); } The printing process is somewhat different from the drawing process In a printing process, a printer works as a drawing surface In a drawing process, we already have a form as a drawing surface To print something on a printer, however, we need the printer object The basic steps of a printing process are

Before we discuss the programmatic flow of a printing process, let's look at the conceptual flow Every printing process involves five basic steps, as illustrated in Figure 113

Step 1 Specify a printer In this step we select a printer to be used in the printing process You may want to select a printer from multiple printers available to your application Step 2 Set the printer properties In this step we can set properties such as color, paper tray, paper size, and print quality This step is optional; if we do not set printer properties, the process uses default settings Step 3 Get the printer surface Unlike the drawing surface (a form), which is available on the form's paint event handler, the printer surface is available only through the print-page event handler As such, this step requires creating a print-page event handler One parameter of the event handler is of type PrintPageEventArgs, whose Graphics member represents the printer surface associated with this print-page event handler In Section 1123 we will see how to implement the print-page event handler programmatically Step 4 Draw graphics shapes, lines, curves, text, and images Once we have the printer surface, everything works in much the same way as the drawing process We can call draw and fill methods to draw lines, curves, shapes, text, and images Step 5 Print After we call the draw and fill methods of theGraphics object associated with a printer, the final step is to print the objects
