Presuming that you have cups installed in the normal fashion and a default printer, just
cat xxx.png | lpr
Enjoy.

Avoids the process for a filter (cat) which is doing nothing for you.

While this is true in Centos, if one moves between *nix implementations, it is an unsafe habit to have (using lpr directly), as in early Unix implementations, lpr is occasionally set to _delete_ the file it has just completed printing.

I consider those broken. If there is doubt, a test or review of the docs should let one know. Anyway, no one cares about those "subtleties" anymore. I know I'm pissing in the wind when I bring up stuff like that.

Not to be anal, but then
lpr < filename
should be safe.

BTW, for *any* process like this taht does not handle a file name on a command line, if not fileter is needed (no concatenation, slicing, converting...) it is always more efficient to do an I/O redirection.
lpr <xxx.png
standard shell stuff. I propose we teach "The Right Way" (TM).
