LLPrint opens the previewer. How can I stop this in API?

I want to print to a couple of preview files and then combine them WITHOUT the user seeing a preview.

But the preview window opens on the LLPrint API function each time. I want to stop this. On an earlier version of List and Label this did not happen. Is it a bug or a modification?

Either way, I want to stop this from happening!

Any and all help would be appreciated!!

Hello I’ve migrated from L&L 10 to L&L 16 and I have the exact same problem.
Please I will appreciate any help.
Best regards.
