OK... CUPS is the print daemon, then.

I did this once, and found that there is in /etc/xinetd.d a file called
cups-lpd. It can be activated by "chkconfig cups-lpd on" if you wish to
activate it, and more info can doubtless be found in the documentation.
This will be one possible way you can share your printer.

However, one of the wonderful things about CUPS is that it is pretty much
transparent. If you are running CUPS on both of them, and if there is no
firewall blocking something in between, then the client computer should
magically see every printer in the local network without any user
interference at all. If there _is_ a firewall, you should open TCP port
631. You do not need to do any specific printer sharing at all.

_Can_ you share a printer over NFS? I didn't know that was possible... are
you sure it is?

Find the "redhat-config-switch-printer" tool (or something like that, I
don't know the real name) and make sure that your CLIENT computer also uses
CUPS. Make sure there is no firewall blocking port tcp/631, or open that
port. Leave it there for a few minutes, then go to http://localhost:631 on
the CLIENT computer so you can configure CUPS... there you should be able
to see the network printer all ready for you (although I do not know if the
correct driver or packages is installed automatically).

>I don't know which print daemon is involved.

CUPS.

See if any of the above helps out. The preferred route should be CUPS in
"native" mode, with cups-lpd as a backup. NFS may or may not enter the
picture at all... certainly _I_ have no experience with it, but my
definition of common sense tells me it is not needed. If this does not
help, post again on this thread...
