Print Word files in C# and VB.NET

With GemBox.Document you can do a silent printing or provide a print dialog and print preview, as shown in the examples for printing in WPF and printing in Windows Forms.

You can print Word documents to the default printer or specify any other local or networked printer that's connected to your machine.

The following example demonstrates how to silently print Word files in C# and VB.NET without the user's interaction.

        // If using Professional version, put your serial key below.
        ComponentInfo.SetLicense("FREE-LIMITED-KEY");

        DocumentModel document = DocumentModel.Load("%#Print.docx%");

        // Set Word document's page options.
        foreach (Section section in document.Sections)
        {
            PageSetup pageSetup = section.PageSetup;
            pageSetup.Orientation = Orientation.Landscape;
            pageSetup.LineNumberRestartSetting = LineNumberRestartSetting.NewPage;
            pageSetup.LineNumberDistanceFromText = 50;

            PageMargins pageMargins = pageSetup.PageMargins;
            pageMargins.Top = 20;
            pageMargins.Left = 100;
        }

        // Print Word document to default printer (e.g. 'Microsoft Print to Pdf').
        string printerName = null;
        document.Print(printerName);
    }
}
Imports GemBox.Document

Module Program

    Sub Main()

        ' If using Professional version, put your serial key below.
        ComponentInfo.SetLicense("FREE-LIMITED-KEY")

        Dim document As DocumentModel = DocumentModel.Load("%#Print.docx%")

        ' Set Word document's page options.
        For Each section As Section In document.Sections

            Dim pageSetup As PageSetup = section.PageSetup
            pageSetup.Orientation = Orientation.Landscape
            pageSetup.LineNumberRestartSetting = LineNumberRestartSetting.NewPage
            pageSetup.LineNumberDistanceFromText = 50

            Dim pageMargins As PageMargins = pageSetup.PageMargins
            pageMargins.Top = 20
            pageMargins.Left = 100

        Next

        ' Print Word document to default printer (e.g. 'Microsoft Print to Pdf').
        Dim printerName As String = Nothing
        document.Print(printerName)

    End Sub
End Module

GemBox.Document uses System.Printing namespace for managing print queues and print jobs. To leverage advance printing capabilities, like specifying the printer's paper source (tray) or specifying two-sided (duplex) printing, you can use PrintTicket class.

Using the PrintTicket class, you can create an object that defines or configures desired printer's features. You provide that configuration in the form of an XML stream (by calling PrintTicket.GetXmlStream method) to GemBox.Document's PrintOptions.

Print Word documents in WPF application

Commonly, in WPF applications you would use PrintDialog to enable users to select a printer, configure it, and perform a print job. For example, your user may specify to print only certain pages of a Word document, or to print multiple pages on one sheet of paper, or something else.

The following example demonstrates how you can use PrintDialog to define GemBox.Document's print options. The example also shows how you can use DocumentViewer control for print previewing.

Print Word documents in Windows Forms application

You can use the same DocumentViewer WPF control from the above example to create a print preview in the Windows Forms application as well. You can accomplish this by hosting the WPF control inside the ElementHost Windows Forms control.

Alternatively, you can use PrintPreviewControl and preview the Word document by providing the PrintDocument object to the control. The following example demonstrates how you can render a document's pages as images and draw those images on a PrintDocument.PrintPage event for print previewing.
