Hi everyone,

I'm generating an EPL file in one directory, and trying to print it, bit I finde the next error:

"There os no associated application with the specified file for this operation"

The file is generated correctly, with this code:

   lShipment.CALCFIELDS(EPL);
   lTmpBLob.Blob := lShipment.EPL;
   lTempServerFileName := lFileManagement.ServerTempFileName('.EPL');
   lFileManagement.BLOBExportToServerFile(lTmpBLob,lTempServerFileName);
   FileNameServer := '\\SRV-DC01\navision\XML\Pegatinas\'+lShipment."No."+'.EPL'; 
   lFileManagement.DownloadToFile(lTempServerFileName,  FileNameServer);

And I'm trying to print it this way:

   IF ISNULL(ProcessStartInfo) THEN
     ProcessStartInfo := ProcessStartInfo.ProcessStartInfo;
   ProcessStartInfo.UseShellExecute := TRUE;
   ProcessStartInfo.Verb := 'Print';
   ProcessStartInfo.WindowStyle := ProcessWindowStyle.Hidden;
   //seleccionar impresora
   ProcessStartInfo.Arguments :='Etiquetas Expediciones 2';
   ProcessStartInfo.FileName := FileNameServer;
   Process.Start(ProcessStartInfo);
   Process.Close;

This are the involved variables
ProcessStartInfo   DotNet   System.Diagnostics.ProcessStartInfo.'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
ProcessWindowStyle   DotNet   System.Diagnostics.ProcessWindowStyle.'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'
Process   DotNet   System.Diagnostics.Process.'System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

What could be the problem? I'm trying different options, but I can't finde the correct way,

Any hint will be really appreciated

Seems to be an issue with the EPL, if I create the file in text mode, I don't get the error...

Hi,

You must apply a Standard Application for the file type EPL and the machine your code is executed (on the client or on the server?)

This must be done in Windows. The way to do it differs from version to version: www.howtogeek.com/.../how-to-set-your-default-apps-in-windows-10

The code below basically emulates as you as a user would click with the right mouse button on that file and select "Print" from the context menu.

IF ISNULL(ProcessStartInfo) THEN ProcessStartInfo := ProcessStartInfo.ProcessStartInfo; ProcessStartInfo.UseShellExecute := TRUE; ProcessStartInfo.Verb := 'Print'; ProcessStartInfo.WindowStyle := ProcessWindowStyle.Hidden; //seleccionar impresora ProcessStartInfo.Arguments :='Etiquetas Expediciones 2'; ProcessStartInfo.FileName := FileNameServer; Process.Start(ProcessStartInfo); Process.Close;

Hi Hannes, thanks for your tip.

What type off aplication should I USe as default one?

As you say about the right click, I've noticed that if I right click the EPL file, I don't have the print option. I understand that this issue will be solved adding the default app, am I right?

edit:

I've configured Notepad++ as the default app:

But I still have the same problem, and still don't having the "Print" button when i right-click on the file.

Should I restart the server?

Than you, really appreciate your help

You must select a program which is able to handle EPL-files.

I'm trying to first print the epl file from commnad line yo see if it's correct, but I'm not able to do it. I'm trying like this:

NET USE 192.168.2.185_6: "\Etiquetas Expediciones 2" /persistent:yes PRINT /D:192.168.2.185_6 C:\XML\ENVIALIA\Pegatinas\ENV18-000059.epl

or

COPY /B C:\XML\ENVIALIA\Pegatinas\ENV18-000059.epl 'Etiquetas expediciones 2'

But I'm not able. Ther printer is configured in the server like this:

You need an application which is able to open and print EPL-files.

It's the same for PDF: You need an application to open and print pdf-files.

If this is not possible, you must consider to generate another file type than EPL.

Thanks Hannes, At first, the development was in PDF, but we need to change it becasue system provider's requirements. I understand perfectly what you're saying, but..

Which application can dothat? I've tried with 2 different ones, but seems not to be the correct ones...

Realy appreciated your tips

I assume EPL is for a barcode printer.

Have a look for the documentation of your printer model to find out how to send EPL-files to the printer directly.

Never did it that way, but I think they provide normally small command line tools or a .NET-integration to communicate with the printer directly.
