DefinePrintOptions Event

In This Topic

This event can be used to set additional options to be used for print/export.

Internally, the event is triggered after the print/export process is started; but before the actual printing starts. This allows you to define various export options using the ExportOptions property or set special print options using LlPrintSetOption and LlPrintOption.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Event DefinePrintOptions As DefinePrintOptionsHandler

public event DefinePrintOptionsHandler DefinePrintOptions

public:
event DefinePrintOptionsHandler^ DefinePrintOptions

Example

If the number of copies is to be defined for label printing, this can be done with LlPrintOption.Copies.

C#
VB.NET

...
// Define label as project type
LL.AutoProjectType = LlProject.Label;

// Register event for defining additional print options
LL.DefinePrintOptions += LL_DefinePrintOptions;

// Print
LL.Print();
...

private static void LL_DefinePrintOptions(object sender, EventArgs e)
{
    // Get the calling List & Label object
    ListLabel senderLL = sender as ListLabel;

    // Define amount of hardware copies
    senderLL.Core.LlPrintSetOption(LlPrintOption.Copies, 2 /* amount of copies */);
}

                
...
' Define label as project type
LL.AutoProjectType = LlProject.Label

'Register event for defining additional print options
AddHandler LL.DefinePrintOptions, AddressOf LL_DefinePrintOptions

' Print
LL.Print()

...

Sub LL_DefinePrintOptions(sender As Object, e As EventArgs) Handles LL.DefinePrintOptions

    ' Get the calling List & Label object
    Dim senderLL As ListLabel = TryCast(sender, ListLabel)
   
    ' Define amount of hardware copies
    senderLL.Core.LlPrintSetOption(LlPrintOption.Copies, 2)

End Sub
