Printing PDFs Programmatically in C#

This guide explains how to print a PDF document or an image programmatically with GdPicture.NET SDK.

Printing and scanning aren’t supported in the cross-platform .NET 6.0 assembly. For more information, see the system compatibility guide.

Printing a PDF Document

To print a PDF document programmatically, follow these steps:

Create a GdPicturePDF object.
Load the source document by passing its file path to the LoadFromFile method.
Optional: Enable the printer settings dialog by storing the handle of the active windows in a variable and then passing this variable to the PrintShowPrinterSettingsDialog method. To print silently, skip this step.
Optional: Configure the printing process programmatically. For more information, see the configuring printing guide.
Print the document with the Print method.
Release unnecessary resources.

using GdPicturePDF gdpicturePDF = new GdPicturePDF();
// Load the source document.
gdpicturePDF.LoadFromFile(@"C:\temp\source.pdf");
// Store the handle of the active window in a variable.
IntPtr WINDOW_HANDLE = IntPtr.Zero;
// Enable the printer settings dialog.
gdpicturePDF.PrintShowPrinterSettingsDialog(WINDOW_HANDLE);
// Print the document.
gdpicturePDF.Print();
// Release unnecessary resources.
gdpicturePDF.CloseDocument();

Using gdpicturePDF As GdPicturePDF = New GdPicturePDF()
    ' Load the source document.
    gdpicturePDF.LoadFromFile("C:\temp\source.pdf")
    ' Store the handle of the active window in a variable.
    Dim WINDOW_HANDLE = IntPtr.Zero
    ' Enable the printer settings dialog.
    gdpicturePDF.PrintShowPrinterSettingsDialog(WINDOW_HANDLE)
    ' Print the document.
    gdpicturePDF.Print()
    ' Release unnecessary resources.
    gdpicturePDF.CloseDocument()
End Using

Printing an Image

To print an image programmatically, follow these steps:

Create a GdPictureImaging object.
Load the source document by passing its file path to the CreateGdPictureImageFromFile method.
Optional: Enable the printer settings dialog by storing the handle of the active windows in a variable and then passing this variable to the PrintShowPrinterSettingsDialog method. To print silently, skip this step.
Optional: Configure the printing process programmatically. For more information, see the configuring printing guide.
Print the image with the Print method.
Release unnecessary resources.

using GdPictureImaging gdpictureImaging = new GdPictureImaging();
// Load the source image.
int imageId = gdpictureImaging.CreateGdPictureImageFromFile(@"C:\temp\source.png");
// Store the handle of the active window in a variable.
IntPtr WINDOW_HANDLE = IntPtr.Zero;
// Enable the printer settings dialog.
gdpictureImaging.PrintShowPrinterSettingsDialog(WINDOW_HANDLE);
// Print the image.
gdpictureImaging.Print(imageId);
// Release unnecessary resources.
gdpictureImaging.ReleaseGdPictureImage(imageId);

Using gdpictureImaging As GdPictureImaging = New GdPictureImaging()
    ' Load the source image.
    Dim imageId As Integer = gdpictureImaging.CreateGdPictureImageFromFile("C:\temp\source.png")
    ' Store the handle of the active window in a variable.
    Dim WINDOW_HANDLE = IntPtr.Zero
    ' Enable the printer settings dialog.
    gdpictureImaging.PrintShowPrinterSettingsDialog(WINDOW_HANDLE)
    ' Print the image.
    gdpictureImaging.Print(imageId)
    ' Release unnecessary resources.
    gdpictureImaging.ReleaseGdPictureImage(imageId)
End Using
