Does a WPF DocumentPaginator document keep all documents in memory until it finishes the print job?

Strictly theoretical question regarding WPP DocumentPaginator:

When using the WPF DocumentPaginator class to print a multi-page document, does the keeper of all the documents it requests remain in the folder during the history of the print job in memory until the document finishes printing? Or does he ever dispose of any documents that he no longer needs before completing a print job (i.e., to free up memory)? Is there a way to manually tell paginator to free old / unnecessary DocumentPages during printing without exception?

Thanks so much for your help in this!
