How to find MAC addresses on network?

Is there a (reasonably) straightforward way of finding the MAC
addresses of systems (well, strictly, interfaces) on a network?

arping works for some but not all of my hardware, presumably some
things (like my HP printer) don't respond to arping.  What can I use
to find the MAC address of the printer?
