I cannot say that you're out of luck with the XP FW and accessing the
print server. The part of the PS using different high ports may be an
issue. In just looking at the rules that can be made with the XP FW, it
may hard to accomplish. What you need is FW that will allow you to set
rules for a private side LAN IP or range of IP(s) that the FW will allow
traffic, assuming that the printer sever has an IP. That way you're not
concerned about the port(s) the traffic is coming in on.
If you're behind a router, then you should be able to use IPsec to
protect the machine and set rules for LAN side IP(s). The AnalogX file if
you implement it on the machine should give you a good foundation for
setting-up LAN side IP(s) rules.

You can use IPsec or another PFW solution that will allow FW rules by IP
to be given.
I have a print server on my network and my laptop that has BlackIce
installed has no problems with LAN side IP(s) behind the Watchguard FW
appliance that issuing DHCP IP(s), because of LAN IP(s) rules that allow
BI on the laptop to allow traffic flow.
