I have a printer using a built in print server with internal IP address
(192.168.2.21) over a remote network and then I assigned on the remote
router that IP address in the DMZ so it's open to the public with an IP
address like 64.64.2.2 that could be reached over the internet.

How do I have to setup in my SCO box to be able to print to that internet
printer with IP address of 64.64.2.2 ? I noticed that SCO's remote printing
capability requires a remote sco box doing the print server function.

Thanks

Unless I'm missing something here (or you are not supplying all of the
information), you don't need to do anything with DMZ on the router.
Do the users at the remote already have access to the SCO system?

Assuming 'yes' to the above, have a look at

You mya not want to put it in the DMZ. If your unspecified router has
a DMZ on the WAN side, then you will need a routeable IP address for
the DMZ print server that is different from the IP address of the NAT
router. If your unspecified router router has the DMZ on the LAN
side, you will need to be sure that the LAN IP address of the print
server is static (192.18.2.21) and that all port numbers that need to
be seen from the WAN side are redirected to this static address.

See:
http://www.hp.com/cposupport/network.../bpj01014.html
for a collection of port numbers used by various HP print servers. Do
not redirect all of them.

For lpr/lpd, you need to redirect port 515.

For HPNP, you need to redirect port 9100 and possibly 9101 and 9102 if
it's a multiport print server. In addition, SCO HPNP uses SNMP to
obtain status information on the OSR5 *CLIENT* machine. You will get
a weird irrelivent error message (which I forgot) if the client
running HPNP fails to get SNMP info. The easy fix is to simply rename
/etc/getone to /etc/getone- which effectively disarms SNMP. Lacking
SNMP, the client machine assumes that the print server is always ready
and printing works as expected.

For Netcat, you'll need to redirect port 9100 and possibly 9101 and
9102 if it's a mutliport print server.

If your unspecified print server is something other than HP, or you're
using a different protocol (i.e. Windoze NETBIOS printing via SAMBA),
kindly disclose some details as it's a bit messy.

No, the destination print server does NOT need to be an SCO server.
It can be an ordinary print server.

Duh. I left out a paragraph. Blundering onward...

Since your unspecified print server already has a LAN side,
non-routeable IP address, there is no need to put it in the DMZ. It
can be on the LAN side, with just the necessary IP port numbers
redirected from the WAN side to the print server IP address. The only
reason I could think of putting a print server on the DMZ WAN side is
if you're running multiple services (Internet Printing Protocol,
Appletalk, Netware, etc) or insist on doing remote maintenance and
configuration via HTTP or telnet. Putting it in the DMZ on the WAN
side effectively opens *ALL* the IP ports to the internet, which makes
it somewhat of a security risk (for the print server). I have one
printer sitting on the internet which gets its web server attacked by
various bots and worms, and is constantly getting hung.

You do not need another SCO box to control the printer server. As long as
the print server uses the LPD daemon, you can configure it into SCO. Look
for mkdev rlp.
