Print Method

PrintDocument.Print Method ()


Starts the document's printing process.

Namespace:   System.Drawing.Printing
Assembly:  System.Drawing (in System.Drawing.dll)

public void Print()

Exception Condition

The printer named in the PrinterSettings.PrinterName property does not exist.

Specify the output to print by handling the PrintPage event and by using the Graphics included in the PrintPageEventArgs.

Use the PrinterSettings.PrinterName property to specify which printer should print the document.

The Print method prints the document without using a print dialog. Use a PrintDialog when you want to offer the user the ability to choose print settings.


If an exception that is not handled by the Print method is thrown during printing, the printing of the document is aborted.

The following code example prints the file that is specified through the command line to the default printer.


The example requires that each line fits within the page width.

Use the System.ComponentModel, System.Drawing, System.Drawing.Printing, System.IO, and System.Windows.Forms namespaces for this example.

         float leftMargin = ev.MarginBounds.Left;
         float topMargin = ev.MarginBounds.Top;
         String line=null;

         // Calculate the number of lines per page.
         linesPerPage = ev.MarginBounds.Height  / 
            printFont.GetHeight(ev.Graphics) ;

         // Iterate over the file, printing each line.
         while (count < linesPerPage && 
            ((line=streamToPrint.ReadLine()) != null)) 
            yPos = topMargin + (count * printFont.GetHeight(ev.Graphics));
            ev.Graphics.DrawString (line, printFont, Brushes.Black, 
               leftMargin, yPos, new StringFormat());

            ev.HasMorePages = false;

               pd.PrintPage += new PrintPageEventHandler(pd_PrintPage);
