I have an HP Photosmart 3210 All-in-One color printer.  Printing works
great, but I cannot get xsane to locate it on the local subnet.

I've been to the sane site and looked at the backends. The HP 3210 is
supported by hpio and there is a note that hpio is no longer needed
because the functionality has been rolled int hplip. yum shows hplip is
hplip.x86_64     1.6.7-4.1.el5.4     installed

Everything is on an internal nat address space.  Host is at .1,
Photosmart is at .251

/etc/services contains an entry for sane-port

xinet.d/ has a file for sane and sane-port (both identical)

iptables allows all outbound and established.

I've gone through several sets of guidance found on the Intenet. Almost
all is for usb or scsi. Very little guidance on sane-net. Finally found
one good set of guidance and followed it to configure dll.conf, and
net.conf.  I've looked at sane.net man page untill I'm cross-eyed.

Anyone successfully scanning from an HP Photosmart network printer?
