The printf() library function is not part of coreutils.  You need to
look elsewhere for help.  You will find some guidance at
http://www.catb.org/~esr/faqs/smart-questions.html.

But you are printing arbitrary binary data as if it were
human-readable text.  What did you _expect_ to see?  If you directly
send the binary data within an image file to a terminal device (e.g.
with cat) you would get a similar result.
