PrintingSystemBase.StartPrint Event

Occurs before the printing system’s document is printed.

Namespace: DevExpress.XtraPrinting

Assembly: DevExpress.Printing.v24.1.Core.dll

NuGet Package: DevExpress.Printing.Core


public event PrintDocumentEventHandler StartPrint

Event Data

The StartPrint event's data class is PrintDocumentEventArgs. The following properties provide information specific to this event:

Property Description
PrintDocument Gets the object that sends the document’s output to a printer.
PrinterSettings Provides access to the corresponding printer settings.


You can use the StartPrint event to change printing settings just prior to printing the document. Use the e.PrinterSettings property to set up the printer settings.

Consider the following specifics of raising this event from UI for Windows environments:

  • In Windows Forms applications, this event is raised after clicking the Qucik Print or Print toolbar button.
  • In WPF applications, this event is raised after clicking the Quick Print toolbar button or the OK button in the Print Dialog.


The following example demonstrates how to use the PrintDocumentEventArgs object when handling the PrintingSystemBase.StartPrint event. The example below demonstrates how to programmatically select a printer to print a document at runtime.

using System;
using System.Windows.Forms;
using System.Drawing.Printing;
using DevExpress.XtraPrinting;
using DevExpress.Utils;
// ...

// creating a PrintingSystem object
private PrintingSystem printingSystem1 = new PrintingSystem();

private void button1_Click(object sender, System.EventArgs e) {
   // handling the StartPrint event
   printingSystem1.StartPrint += new PrintDocumentEventHandler(printingSystem_StartPrint);

   // printing the document

private void printingSystem_StartPrint(object sender, PrintDocumentEventArgs e) {
   // setting the specific printer's name before printing
   e.PrintDocument.PrinterSettings.PrinterName = PrinterSettings.InstalledPrinters[1];
