Hi, 

the tab to configure printers only appears on web browser when you access the following url : http://localhost:631/admin/

Hello Stefan,
 Thank you for your response.

http://localhost:631/admin

By using the above URL, I was able to add a virtual pdf printer. But as you said, I tried adding the printer into my program by Javascript. But there is no success. Can you share me an example on how to exactly add the printer to the event CreateScreenshot in Unified panel.
Or any other suggestions to create a screenshot and save it as PDF into the USB.
Any suggestions would be much appreciated.
Thank you in advance.

 
With regards
John

Createscreenshot function will save it as a PNG (not a pdf). It may be good enough for you?

Hello Franck,
PNG format should also be fine. But I am not able to find it in the USB stick. The stick is logging the alarms, trend and other things. I am able to see those files. But No Screenshot images.

As you can see from the attachment, I have created a button for screenshot. In the event of press, I have added the function with the path for storage. Still I am not able to get the image in my USB stick.

Any suggestions as to why or where am I going wrong. 
Thank you in Advance.

Regards
John
