I get it now on a new from scratch installed openSUSE 12.1
when I switch directly after the installation finished
to a system text console and there run as root:

# rccups status
redirecting to systemctl
cups.service - LSB: CUPS printer daemon
Loaded: loaded (/etc/init.d/cups)
Active: active (exited) since Fri, 25 Nov 2011 12:51:41 +0100; 15min ago
Process: 10493 ExecStart=/etc/init.d/cups start (code=exited, status=0/SUCCESS)
CGroup: name=systemd:/system/cups.service

# lpinfo -m
lpinfo: Unknown

#echo $?
1

Therefore this is not an issue in YaST because it is "lpinfo" itself
which returns with "lpinfo: Unknown" and non-zero exit code.

After a few minutes waiting "lpinfo -m" works.

In the CUPS 1.5.0 sources in systemv/lpinfo.c there is a few times
---------------------------------------------------------------------
_cupsLangPrintf(stderr, "lpinfo: %s", cupsLastErrorString());
..
return (1);
---------------------------------------------------------------------

Currently I don't know the root cause that lets lpinfo
initially fail with "lpinfo: Unknown".
