How to print a remote file from NAV

I have seen couple of times the requirement where we need to print a document from NAV which is not a report, it could be a marketing campaign letter, sales sheets or any other document.

Most of the time we upload these kind of documents on a website/remote site, so if we need print those documents with every invoice or any other statement, below is the function you can use from NAV.

In the below example I just took a random PDF URL from the web and used it for testing.

The key in this function is to download the document from the web using WebClient locally and then use the Process to print the document to the printer.

LOCAL PROCEDURE PrintRemoteFile@1240060002();
     VAR
       FileURL@1240060000 : Text;
       ProcessStartInfo@1240060001 : DotNet "'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Diagnostics.ProcessStartInfo";
       Process@1240060002 : DotNet "'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Diagnostics.Process";
       WebClient@1240060003 : DotNet "'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Net.WebClient";
       LocalFileName@1240060004 : Text;
     BEGIN
       FileURL := 'http://che.org.il/wp-content/uploads/2016/12/pdf-sample.pdf';
       ProcessStartInfo := ProcessStartInfo.ProcessStartInfo();
       WebClient := WebClient.WebClient();
       LocalFileName := 'C:\Temp\TempFile.pdf';
       WebClient.DownloadFile(FileURL,LocalFileName);
       ProcessStartInfo.FileName := LocalFileName;
       ProcessStartInfo.Verb := 'Print';
       ProcessStartInfo.CreateNoWindow := FALSE;
       Process := Process.Process;
       Process := Process.Start(ProcessStartInfo);
       MESSAGE('Document Printed');
     END;
