Use a script to create a multipage PDF document using PDFCreator

I am trying to script an application to print out a report. The report is made up of several individual pages that I would like to save as a single PDF document.

What is the easiest way to print several pages to PDFCreator, collect them into a single PDF and save out the document with a specified name to a specified location? 

I would like something like what is acomplished with auto-save but I need to collect 6-7 pages together.

Take Care.
