Comment # 1 on bug 944012 from Johannes Meixner

It seems it happens only with CUPS 2.x

With CUPS 1.7.5 on SLE12 there is no such delay:
-----------------------------------------------------------------------------
# lpstat: Unable to connect to host.

real    0m0.010s
user    0m0.004s
sys     0m0.000s
-----------------------------------------------------------------------------

With CUPS 1.3.9 on SLE11 there is no such delay:
-----------------------------------------------------------------------------
# time lpstat -h -p
lpstat: Unable to connect to server

real    0m0.010s
user    0m0.004s
sys     0m0.000s
