While solving some special remote printing problems I saw (4.2-STABLE) that lpd verifies printer access from a remote host by a lot of name resolution requests (my /etc/hosts.lpd has more than 300 entries). When verifying a host lpd scans hosts.lpd from the first line to the first matching line *not* by string comparison (hostname) but by requesting a name resolution for each entry (line by line) and comparing the INET address. For a heavily loaded printer server (as mine is) this seems not be a good idea ... but maybe there's a good reason to to this?
