I just called and had the printer (hplaserjet 1300) reconnected to the
old server and it works fine with hplip ver. 1.6.7 so I don't think it's
hplip. Both machines are identical except for motherboard, ram and
drives, none of which should be in the picture here AFAIK. Even had the
cat5 cable switched between the two boxes with no change. Don't think I
have ever seen a port closed with the firewall down and a service
running on it before. You may be right, it may be a bug but I've done
this so many times on centos 5 without this issue. Thanks for all your
help. I'll keep plugging at it and if all else fails try another
install.
