I have a webservice that has a crystal report that generates an invoice from my database and then exports the crystal to a PDF, into a stream and then returns as a string on the web method.

On the client side I have a Winforms C# app that calls this webservice. I would like to be able to automatically print the PDF on the client side without opening Acrobat Reader.

I would preferably not want to save the PDF either because currently I have to save the开发者_如何转开发 PDF then use a process to open Acrobat Reader and then print the PDF.

There is a free utility called SumatraPDF that lets you print PDF documents silently. I have succesfully used it in a winform app.

private void print(string printerName, string fileName)
        {
            try
            {
                System.Diagnostics.Process proc = new System.Diagnostics.Process();
                proc.StartInfo.FileName = "SumatraPDF.exe";
                proc.StartInfo.Arguments = "-print-to " + '"' + printerName+ '"' + " " + '"' + fileName+ '"';
                proc.StartInfo.RedirectStandardError = false;
                proc.StartInfo.RedirectStandardOutput = false;
                proc.StartInfo.UseShellExecute = true;
                proc.Start();
                proc.WaitForExit();
            }
            catch (Exception ex)
            {
                EventLog.WriteEntry("InboundServicioImpresion", ex.Message + " " + ex.StackTrace);
            }
        }

For the "automatic print", you could use a Timer or a infinite loop that executes the method above.

I had a similar challenge. The solution I've made was buying a component called PDFTron. It has an API to send pdf documents to a printer from an unattended service. I posted some information in my blog about that. Take a look!

How to print a PDF file programmatically???

Thanks,

You could use the command line:

acrord32 /t "out.pdf" "Acrobat Distiller" "AdobePS Acrobat Distiller" "in.pdf"

The syntax is:

acroRd32.exe /t path printername drivername portname

• Initiates Acrobat Reader, prints a file while suppressing the Acrobat print dialog box, then terminates Reader.
