In this article I will show you the results of my search to find a way to print a pdf with .NET.
My task was to find a simple solution for an intranet web application where the user gets pdf reports (ActiveReports). Depending on configuration settings these pdf files should be displayed in the browser and be printed immediately or just be printed immediatly – to the default printer or to a known network printer.
The existing solution was based on the pdf browser plugins. But it was not satisfactory because the user had to do the following steps: view the pdf file in the browser (pdf browser plugin), click the print button, handle the printer dialog popup, click the OK button to send the document to the printer. And some users had to do this more then one hundred times a day. And some users had to do this more than a hundred times a day!
My (more than revolutionary 
idea was, that I may need the pdf browser plugin for viewing pdf files, but not for printing them! So I tried different ways, which I wanted you to show now – I did not bring all of them to an end, as some turned out to be inappropriate for my intentions very soon.
Important: these solutions are only making sense if you want to print to a known printer (like in intranets) – they will not work on normal, “public” web sites.
You can download the sample project and do your own experiments. Here is a screenshot of the sample project:
My results:
- Printing a pdf with Ghostscript
- Printing a pdf with windows shell command
- Printing a pdf with PrintDocument object
- Printing a pdf with PDFsharp
- Printing a pdf with Acrobat Reader command line
First you have to install Ghostscript, an interpreter for the PostScript language and for PDF. Code:
ProcessStartInfo psInfo = new ProcessStartInfo();
psInfo.Arguments = String.Format(" -dPrinted -dBATCH -dNOPAUSE -dNOSAFER -q -dNumCopies=1 -sDEVICE=ljet4 -sOutputFile=\"\\\\spool\\{0}\" \"{1}\"", printerName, pdfFileName);
psInfo.FileName = @"C:\Program Files\gs\gs8.70\bin\gswin32c.exe";
psInfo.UseShellExecute = false;
Process process = Process.Start(psInfo);
This is another version I found on the web. The code uses the print/printto command of the DOS shell. In the example project, which you can download above, there are two versions of parameters in the code. I never got it work, but I think, it cannot be done: you cannot print a pdf file via shell – but it will work with raw text files. Please tell me your results!
Try this in your DOS prompt:
print /D:"\\COMPUTERNAME\PRINTERNAME" "PDFFILEPATH"
For those who want to try it themselves
ProcessStartInfo psInfo = new ProcessStartInfo();
psInfo.Verb = "Print"; // or "PrintTo"
psInfo.FileName = pdfFileName;
psInfo.Arguments = String.Format("/p /h \"{0}\" \"{1}\"", pdfFileName, printerName);
psInfo.WindowStyle = ProcessWindowStyle.Hidden;
psInfo.CreateNoWindow = true;
psInfo.UseShellExecute = true;
Process process = Process.Start(psInfo);
Using the .NET object PrintDocument is another possible way, but you will need third party components to raster the pdf. More information: >>Component for rendering pdf documents
PrintDocument pd = new PrintDocument();
pd.DocumentName = pdfName;
pd.PrinterSettings.PrinterName =printerName;
pd.PrinterSettings.PrintFileName = fileName;
pd.PrintController = new StandardPrintController();
pd.OriginAtMargins = false;
pd.PrintPage += new PrintPageEventHandler(this.pd_PrintPage);
pd.Print();
PDFsharp is an open source .NET library for processing PDF. You can use it for printing too. Simple usage, but the problem here: the AdobeReader application window appears (not suitable for my intentions). But I found out that you do not need PDFsharp to print out a pdf – see chapter 5
PdfFilePrinter.AdobeReaderPath = @"C:\Program Files\Adobe\Reader 9.0\Reader\AcroRd32.exe"
PdfFilePrinter printer = new PdfFilePrinter(pdfFileName, printerName);
printer.Print();
This was the best way for me! Although I’ve read that this only works with old versions of Acrobat Reader, it works with version 9.0!
A word to the arguments:
print it to the default printer: /s /o /h /p “pdfFileName”
print it to a defined printer: /s /o /h /t “pdfFileName” “printername” “drivername” “portname”
More information at the Adobe Acrobat Developer FAQ on page 27!
To download the free acrobat reader use this link: Acrobat Reader
ProcessStartInfo psInfo = new ProcessStartInfo();
psInfo.FileName = @"C:\Program Files\Adobe\Reader 9.0\Reader\AcroRd32.exe";
psInfo.Arguments = String.Format("/s /o /h /p{0}", pdfFileName);
psInfo.WindowStyle = ProcessWindowStyle.Hidden;
psInfo.CreateNoWindow = true;
psInfo.UseShellExecute = true;
Process process = Process.Start(psInfo);
