Printing Overview(all you need to know) Create a new PrintDocument object Set printer settings through the PrinterSettings property

Set page settings through the DefaultPageSettings property

Call the Print method to start the printing process

Handle the PrintPage event where you specify the output to print, by using the Graphics object included in the PrintPageEventArgs










Basic Printing: create a new PrintDocument object Either drag an instance of the PrintDocument

object directly from the Toolbox to the designer at design time …

or use code at run time. Visual Basic .NET

Imports System.Drawing.PrintingDim myPrintDocument As _ New PrintDocument()

Visual C#

using System.Drawing.Printing; PrintDocument myPrintDocument = new PrintDocument();

Uses default settings on the default printer


Basic Printing: the PrintPage event and its handler Call the Print method to start printingPrintDoc1.Print()

One PrintPage event is raised for each page Handle this yourself Use the PrintPageEventArgs.Graphics object

to specify the output to print Private Sub PrintDoc1_PrintPage( _ ByVal sender As System.Object, _ ByVal e As PrintPageEventArgs) _ Handles PrintDoc1.PrintPage... e.Graphics.DrawString( _ "G'day World", ... e.HasMorePages = FalseEnd Sub
