How can I disable print preview with API

I am printing a couple of jobs to print preview files and then combining them with LLStgsysAppend. Everything works fine, except the Print Preview opens ( seemingly automatically) after each print preview file is created. I DON’T want this, I simply want the file created.

How can I turn off the print preview so the users don’t see it?

I solved it!! Just use LLSetOption with LL_OPTION_INCREMENTAL_PREVIEW set to false.
