What is the complete list of file formats that CUPS supports?  (i. e. what file types can I feed to lpr directly without having to convert them first?)I have been searching for the answer and haven't found anything specific.  The best I've been able to find is CUPS understands many different types of files directly, including text, PostScript, PDF, and image files.  But this is still fairly vague; in particular, what image file formats does it accept?Thanks!
