There are a dozen reasons two hosts could have the same IP, and most of
them don't deal with DHCP.  Someone could have brought up and old host
that used to have the IP, or someone could have been fooling around with
their own IP settings for a minute or two.  The DHCP server could have
goofed.  And even the router (if there is one) between you and the
printers could have goofed.  And someone could have hooked up a personal
laptop and just stolen the printer IP, hoping no one would notice.
