Performance of PrintDocumentWithSettings

Aspose.PDF Product Family
1

I am using PdfViewer.PrintDocumentWithSettings to send an existing pdf file to a local printer. I compared its performance with Acrobat Reader and PDFtoPrinter. It turns out that PdfViewer.PrintDocumentWithSettings is 3 times as slow for a pdf containing 100 pages.

I am using Aspose.PDF 25.3.0.

Is there a way to speed up the printing?

Changing PrintAsImage, AutoResize, AutoRotate does not have much impact on the printing time. It is still a lot slower than Acrobat Reader and PDFtoPrinter. Also using Aspose.PDF 25.5.0. does not change these printing times.

The performance of the PdfViewer.PrintDocumentWithSettings method can vary, and it seems you are experiencing slower printing speeds compared to other applications like Acrobat Reader and PDFtoPrinter. Here are some suggestions to potentially improve the printing speed when using Aspose.PDF:

  1. Update to the Latest Version: Ensure you are using the latest version of Aspose.PDF. The library has undergone various updates, and newer versions may include performance improvements and bug fixes. As of your current version (25.3.0), consider upgrading to a more recent release.

  2. Optimize Print Settings: Review the settings you are using for printing. For instance, setting AutoResize and AutoRotate to true can sometimes add overhead. If these features are not necessary for your use case, try disabling them to see if it improves performance.

  3. Use Print As Image: If your document contains complex graphics or fonts, consider using the PrintAsImage property. This can sometimes speed up the printing process, especially for documents with intricate layouts.

  4. Adjust Page Settings: Ensure that the page settings (like margins and paper size) are set appropriately. Unnecessary margins or incorrect paper sizes can lead to additional processing time.

  5. Batch Printing: If you are printing multiple documents, consider batching the print jobs. This can reduce the overhead of initializing the print process multiple times.

  6. Monitor Print Job Status: Implementing a way to check the status of the print job can help you identify if there are any delays or issues during the printing process.

Here is a sample code snippet that demonstrates how to set up the PdfViewer for printing:

public static void PrintPDF(string filePath)
{
    PdfViewer viewer = new PdfViewer();
    viewer.BindPdf(filePath);
    
    viewer.AutoResize = false; // Consider setting this to false
    viewer.AutoRotate = false; // Consider setting this to false
    viewer.PrintPageDialog = false;

    Aspose.Pdf.Printing.PrinterSettings ps = new Aspose.Pdf.Printing.PrinterSettings();
    Aspose.Pdf.Printing.PageSettings pgs = new Aspose.Pdf.Printing.PageSettings
    {
        PaperSize = new Aspose.Pdf.Printing.PaperSize("A4", 827, 1169),
        Margins = new Aspose.Pdf.Devices.Margins(0, 0, 0, 0)
    };

    viewer.PrintDocumentWithSettings(pgs, ps);
    viewer.Close();
}

By following these suggestions and optimizing your settings, you may be able to enhance the printing performance of your PDF documents using Aspose.PDF. If the issue persists, consider reaching out to Aspose support for further assistance or to report any potential bugs.
