How to print a file (word doc, pdf or infopath form) from a URL using code?

[bin_bin1]

Hello there, I am trying to print a file(could be word, pdf or infopath form) from URL using c# code. But I always got "The parameter is incorrect" error. The following is the code that I used. WindowsImpersonationContext wic = WindowsIdentity.GetCurrent().Impersonate(); Process printJob = new Process(); printJob.StartInfo.FileName = @"http://testsrv/test1/Shared Documents/test.txt"; printJob.StartInfo.UseShellExecute = true; printJob.StartInfo.Verb = "print"; printJob.Start(); I am sure the URL is correct. I also tried to download the file to local drive and use the local full file path instead. In that case, it doesn't print and there is no exception either. I am really confused. Please help. My code is running in an ashx handler. I don't know whether that makes different or not. Thank you very much in advance. Bin

So your code is running on the server, isn't it?
