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.
