Thus spake Hajimu UMEMOTO (ume@mahoroba.org):

I started lpd on this machine: (with the -4 flag, see above).

alex@oink ~ $ uname -a ; ifconfig -a
FreeBSD oink.cichlids.com 5.0-CURRENT FreeBSD 5.0-CURRENT #0: Sat Sep  1 15:25:41 CEST 2001     root@oink.cichlids.com:/usr/obj/usr/src/sys/GENERIC  i386

This is the printcap from this machine:

lp|local line printer:\
        :sh:\
        :rm=neutron:\
        :sd=/var/spool/output/lpd:lf=/var/log/lpd-errs:

Note that "neutron" has:
alex@oink ~ $ ping6 neutron
PING6(56=40+8+8 bytes) fe80::250:baff:fed4:a512%rl0 --> fe80:1::250:4ff:fe0f:5a27
16 bytes from fe80::250:4ff:fe0f:5a27%rl0, icmp_seq=0 hlim=64 time=2.492 ms
^X^C

(telnet6 works!)

Then I just start lpd (or lpd -4, same effect), and this happens.
when I do rm=192.168.0.1 in the printcap, I get:
root@oink ~ $ lpq
oink.cichlids.com: Warning: no daemon present
Rank   Owner      Job  Files                                 Total Size
1st    alex       0    (standard input)                      419326 bytes

lpd: Host name for your address (192.168.0.19) unknown

So, this MIGHT be the reason:  The IPv4 address is nonexistent,
but it displays the IPv6 address as error address.
However, it's still bad that he uses and IPv6 stuff when I specify -4

BTW, it works if I add a PTR for 192.168.0.19.
