Ctrl-L is a form feed, and is legitimate whitespace. Your interpreter
should accept it as such. Ctrl-D is often used by serially-connected
PostScript printers to indicate the end-of-file. It is not part of the
PostScript language, and has been used erroneously by the files you are
getting. Complain to whoever generated the files.

11x17 and 11x17tray are references to paper that is 11 inches by 17 inches.
