How to print invoices to file (e.g. PDF) in AX 2009?

Hi,

i'm new to AX 2009. 

I'm looking for a way to put invoices into PDF files. 

I've browsed through EPSendDocument (it looks deprecated, isnt it?), PrintJobSettings, but can't find the proper way to do that. 

At the moment i've got CustInvoiceJour table as the result of a query. How do I print each invoice to PDF file via code?

I've seen many solutions with reports, but i don't have any report available, and don't want to use it if possible. 

Thank you for your help

ciao
