PrintDocument.Print Method

Starts the document's printing process.

[Visual Basic]
Public Sub Print()
[C#]
public void Print();
[C++]
public: void Print();
[JScript]
public function Print();

Exceptions

Exception Type Condition
InvalidPrinterException The printer named in the PrinterSettings.PrinterName property does not exist.

Remarks

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.

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

Example

[Visual Basic, C#, C++] The following example prints the file that is specified through the command line to the default printer.

[Visual Basic, C#, C++] Note   The example assumes that each line fits within the page width.

[Visual Basic, C#, C++] Use the System.ComponentModel, System.Drawing, System.Drawing.Printing, System.IO, and System.Windows.Forms namespaces for this example.
