PDF in horizontal layout

Hi everybody,

I have a problem with a pdf creation. Everything is working fine, I am creating a pdf coming from the spool and I am attaching it to an email. The problem I have is that the information is too large and I would like to show everything, so my idea was to change the layout into horizontal, but I can not see any parameter or whatever to do it. I am using this function 'CONVERT_ABAPSPOOLJOB_2_PDF'.

Does anyone know how to solve it?

Thanks in advance
