NPrinting image quality

[chriswain2]

I have created an NPrinting PowerPoint report. When I schedule the task and the server runs it, the picture quality is very bad. If I run the task manually in the designer immediately after, the picture quality is perfect. I attach two charts copied from the PowerPoint output to show the difference. Does anyone know the cause of this please?

What version of NPrinting are you using?

v16 SR4 has some fixes to improve image quality, the extract below is from the release notes, I'm not sure if this change affects PowerPoint output.

JPEG quality improved in Pdf reports from Office templates

Office reports with JPEG images in the template produced pdfs with low quality images due to a compression during the generation process.

Chris,

One of the things you can do is to increase the image quality in the chart object attributes in the QVW.

Mike Czerwonky can give you more details on how to do this.

I think this is the post Aran is referring to...

Improving Image Quality Export using Clipboard Zoom

Hi Colin / Aran,

Sorry, you have missed the problem I have. The same NPrinting PowerPoint report gives different quality outputs when run by the server and by the designer modules. Why would this be the case? Everything else is the same. I am running version 16 on both modules.

I have just tested it by using the scheduler in the designer module which works fine and then set the schedule and run it via the server and it comes out poor quality again. Nothing else has changed.

It is not just poor quality resolution either. I am also getting cell borders appearing in tables where they do not exist in the qvw.

Thanks,

Chris

Hi Chris,

Here's a shot in the dark - could you check for differences in the QlikView Desktop Settings > User Preferences > Export tab on the machine you run Designer and the one you run Server on? Log into the NPrinting server with the NPrinting server service account credentials when checking. If there are differences and if you match them up do you get consistent results?

I'm also curious to know the version of Windows that your NPrinting server runs on.

Let us know.

Daniel.

Hi Daniel,

The server is on Windows 7. I am running the designer and the server directly on the server using remote desktop and I am logged on as the nprinting user and still get different results. They must be using the same desktop version.

Hi Chris,

And what version of NPrinting do you use? Are Designer & Server the same version? If not on it already, could you upgrade to NPrinting 16.4 and try?

If you still have issues I suggest you open a case with Qlik Tech. Support.

Best,

Daniel.

Hi Daniel,

It is version 16.3.

Thanks for your help - I will do that.

Chris

Chris,

We are getting ready to update to 16.4 as well.  Can you please jump back on here and post if this solved your problem.  I see a number of fixes in the 16.4 release notes that likely would help us.   We are going to 17.1 when it becomes available this summer.
