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();
       FileURL@1240060000 : Text;
       ProcessStartInfo@1240060001 : DotNet "'System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Diagnostics.ProcessStartInfo";
       Process@1240060002 : DotNet "'System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Diagnostics.Process";
       WebClient@1240060003 : DotNet "'System, Version=, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.Net.WebClient";
       LocalFileName@1240060004 : Text;
       FileURL := '';
       ProcessStartInfo := ProcessStartInfo.ProcessStartInfo();
       WebClient := WebClient.WebClient();
       LocalFileName := 'C:\Temp\TempFile.pdf';
       ProcessStartInfo.FileName := LocalFileName;
       ProcessStartInfo.Verb := 'Print';
       ProcessStartInfo.CreateNoWindow := FALSE;
       Process := Process.Process;
       Process := Process.Start(ProcessStartInfo);
       MESSAGE('Document Printed');

If you have any other tips or suggestions to resolve this error, please do share them in the comments below.

Hi Suresh
I tried this code but this is not working for me, do you have any idea why this is not working for me.
The only difference I made in my code is I did not download any file from web, instead I am already having a file in some specified location which I am trying to print.
Here is my code

ProcessStartInfo := ProcessStartInfo.ProcessStartInfo();
WITH ProcessStartInfo DO BEGIN
FileName := 'c:\temp\S076511.pdf';
Verb := 'Print';
CreateNoWindow := FALSE;
WindowStyle := ProcessWindowStyle.Hidden;
Process := Process.Process;

I am getting this error:

A call to system.diagnostics.process.start failed with this message. The system cannot find the file specified

Thanks for your help

Hello Kuljeet,

Did you set the RunOnClient for ProcessStartInfo, Process.. variables to true, if not it will be looking at that file on the NAV server, either you have to download the file to the client machine and print or set the RunOnClient property for the variables to true.

Let me know if that fixes the issue.

Hi Suresh, this solution it's very interesting but i have a question.
If i want to set another Printer and not print with a default printer?
What should I do?

I working on a modification with that specific requirement and I will post the solutions in a new blog in next couple of days. One Solution suggest online is to use the Arguments property for Process Start Info but that did not work for me.
So please check my blog in next couple of days for the solution.

Hi Suresh

I came across your blog on the printing of external documents attached to NAV and see it has been very helpful

my question is, what if the document is attached to a PO in NAV.
How can this document automatically print when printing the PO

Thanks for you help

Hi Suresh,

I am trying to download file from URL, I tried different methods (NAV 2015) but I am getting below error:-

Microsoft Dynamics NAV

A call to System.Net.WebClient.DownloadFile failed with this message: The request was aborted: Could not create SSL/TLS secure channel.

I was looking for solutions then I find your code and used it as below but I am getting same error. It is working in BC 365.

WebClient := WebClient.WebClient();
Credential := Credential.NetworkCredential;
Credential.UserName := ''; //Specified UserName
Credential.Password := ''; //Specified password
WebClient.Credentials := Credential;

WebClient.DownloadFile('URL Address','Local Address');

Can you please suggest what can be issue.
