Printing PDF documents in C# can be achieved without Adobe Acrobat. Using Spire.PDF, developers can easily incorporate powerful printing functionalities into their applications. This library provides a smooth, programmatic method to manage everything from simple printing tasks to advanced features such as duplex printing and silent printing. Whether you need to print a single page or an entire multi-page document, Spire.PDF ensures precision and efficiency.
In this article, we’ll explore how to leverage Spire.PDF for .NET to print PDFs directly from your C# applications , customize print settings, and resolve common issues.
Best C# .NET Library for Printing PDF
When it comes to PDF printing in C#, several libraries are available, but Spire.PDF stands out as one of the most robust and developer-friendly options. Spire.PDF offers:
- Comprehensive PDF manipulation capabilities
- Simple yet powerful printing functionality
- No dependency on Adobe Acrobat
- Support for both Windows Forms and Console applications
- Extensive customization options for print settings
The library handles all the low-level complexities of PDF rendering and printer communication, allowing developers to focus on implementing business logic rather than wrestling with printer APIs.
To begin, install the Spire.PDF for .NET library via NuGet Package Manager :
Install-Package Spire.PDF
Alternatively, you can download Spire.PDF directly from our official website and reference the DLLs in your project.
Basic PDF Printing in C#: Directly Print PDF to Default Printer
Now, let's start with the simplest scenario: printing a PDF document to the system's default printer. Spire.PDF makes this incredibly straightforward:
using Spire.Pdf;
namespace PrintWithDefaultPrinter
{
class Program
{
static void Main(string[] args)
{
// Create a PdfDocument object
PdfDocument doc = new PdfDocument();
// Load a PDF file
doc.LoadFromFile("C:/Users/Administrator/Desktop/Input.pdf");
// Print to default printer
doc.Print();
// Clean up resources
doc.Dispose();
}
}
}
This basic example demonstrates the core workflow:
- Create a PdfDocument instance.
- Load an existing PDF file.
- Call the Print() method to send the document to the default printer.
- Clean up resources.
The simplicity of this approach makes it ideal for scenarios where you just need to quickly print a document without any special requirements.
Advanced Print Settings in Spire.PDF
While the basic printing method works for simple cases, most real-world applications require more control over the printing process. Spire.PDF provides extensive print customization through its PrintSettings property.
1. Specify Printer Name
Instead of using the default printer, you can target a specific printer by name:
doc.PrintSettings.PrinterName = "Your Printer Name";
2. Set Print Page Range
For large documents, you might want to print only specific pages. Use SelectPageRange() to define a start and end page:
doc.PrintSettings.SelectPageRange(1, 5); // Pages 1 to 5
For non-sequential pages, use SelectSomePages() :
doc.PrintSettings.SelectSomePages(newint[] { 1, 3, 5, 7 });
3. Adjust Number of Copies
Need multiple copies? Set the Copies property to the desired number:
doc.PrintSettings.Copies = 2;
4. Enable Duplex (Double-Sided) Printing
Duplex printing can save paper and is commonly required for professional documents. Check if the printer supports it first:
if (doc.PrintSettings.CanDuplex)
{
doc.PrintSettings.Duplex = Duplex.Default;
}
5. Black and White (Grayscale) Printing
For documents where color isn't necessary, you can force grayscale printing:
doc.PrintSettings.Color = false;
6. Silent Printing (Hide Dialog Box & Process)
For automated workflows, you often want to print without any user interaction:
doc.PrintSettings.PrintController = new StandardPrintController();
This suppresses all print dialogs, making the process completely silent. Use this carefully, as it removes the user's ability to confirm or adjust settings.
7. Print Different Pages to Different Trays
Advanced printers with multiple paper trays can handle complex document assembly automatically:
// Register event handler for paper settings
doc.PrintSettings.PaperSettings += delegate (object sender, PdfPaperSettingsEventArgs e)
{
// Use tray 1 for pages 1-10
if (1 <= e.CurrentPaper && e.CurrentPaper <= 10)
{
e.CurrentPaperSource = e.PaperSources[0];
}
// Use tray 2 for pages beyond 10
else
{
e.CurrentPaperSource = e.PaperSources[1];
}
};
This feature allows for professional document production where cover pages, inserts, or chapter dividers can automatically print on different paper stock.
8. Print Multiple Pages Per Sheet
Optimize paper usage by printing multiple PDF pages on a single sheet. The SelectMultiPageLayout() method lets you specify the grid layout (rows × columns) for page arrangement:
doc.PrintSettings.SelectMultiPageLayout(2, 2); // Prints 4 pages per sheet (2 rows × 2 columns)
This setting is ideal for printing booklets, handouts, or draft documents while conserving paper. The pages are automatically scaled to fit the specified layout.

FAQs
Q1: How do I print a PDF in C# without Adobe?
Use Spire.PDF’s Print() method to send the document directly to the printer.
Q2: Can I print PDFs to a network printer?
Yes, as long as the printer is properly installed on your system, you can specify it by name just like a local printer.
Q3: How to print a PDF in WPF or WinFroms?
The code snippets provided in this guide work seamlessly in both WPF and WinForms applications. In WPF, consider adding printer selection dialogs for an enhanced user experience.
Q4: How can I improve print quality when printing PDFs programmatically in C#?
You can control print quality by setting the printer resolution using the PrinterResolutionKind property. For high-quality output, use:
doc.PrintSettings.PrinterResolutionKind = PdfPrinterResolutionKind.High;
Spire.PDF supports these resolution options:
- Low (Draft quality)
- Medium (Standard quality)
- High (Best quality)
- Custom (Requires additional DPI settings)
Note: Actual output depends on your printer's capabilities. For photo-quality prints, ensure your printer supports high DPI (e.g., 1200x1200) and use high-quality paper. Combine this with doc.PrintSettings.Color = true for color-critical documents.
