            1 Redirect output of the print operator to paper. Particularly useful if
            2 you're trying to extract information from a printer, but you don't have
            3 access to the data the printer returns to the host.
            4 
            5 For example,
            6 
            7         FontDirectory {pop ==} forall
            8 
            9 names all the fonts registered in the FontDirectory dictionary. Simple,
           10 but only if you can read the data returned to the host by the printer.
