Basic printing

These are (I guess) the most basic printing instructions in C#, to let some printed paper coming out of a printer.
Start a new Forms application, drop a ComboBox, a Label and a Button on the form. Implement a form Load and a Button Click event and fill in the rest of the above code. I hope the comments in it are sufficient to understand the code. Feel free to ask,if not. If you find any errors in it, or if you have any remarks, please inform me as well.

            foreach (string printer in PrinterSettings.InstalledPrinters)

                comboBox1.Items.Add(printer);

            //Add PrintPage event handler
            PrintDoc.PrintPage += new PrintPageEventHandler(printAPage);

            //It is handy to make the name of the Graphics object smaller
            Graphics G = PE.Graphics;
            //Create a font arial with size 16
            Font font = new Font("Arial", 16);
            //Create a solid brush with blue color
            SolidBrush brush = new SolidBrush(Color.Blue);
            // Create a rectangle
            Rectangle rect = new Rectangle(Xpos, Ypos, 250, 50);
            //Draw text
            G.DrawString("Printing: Hello, World! ", font, brush, rect);
            //Put a red Rectangle around the text
            Pen pen = new Pen(Color.Red);
            G.DrawRectangle(pen, Xpos, Ypos, 250, 50);
            //etc.
        }
    }
