In this case you can just print to the printers IP address. 

What is running the firewall? The DSL modem?

 Their sales oriented operation is mostly take-away laptops, but they
 want the printing to come into the office during their absence but 

Unless the modem can do NAT and has a firewall, I'd definitely put a
server between the modem and the router. That way you can handle
printing with CUPS, firewall with pf, mail, backups etc.

Otherwise you'll have to tell the modem to do NAT, and let traffic from
the laptops through while blocking unwanted stuff. It depends on the
router if the built-in software is up to that, and if you trust it for that.

Just get a printer with a built-in ethernet and set it to a static IP on 
the LAN side of the router.

Well, if your printer has its own Ethernet card and an IP address
you can just set things up to go directly to it with no server.

Or, what is that router?   If it is something like a FreeBSD box or
other more full service system, it can probably handle the task of
serving the printer as well.

I don't want to use a server. So the router would have to do NAT.
Is it possible that way for the outside world to address the 
printer directly since it has a network address, and not a 
www IP?

You can probably setup the router to forward the ports used by that 
printer.  The ports you'd need to forward are dependent on the printer driver.

Just set up your firewall to only allow the addresses you want to
go to that printer.   Some printers with ethernet cards can also
be set to only accept incoming from a list of addresses.

Netopia has them that will either bridge or route with a built-in adsl modem.

If you want more routing capability get a better netopia like a 9000 series 
which you can get with an ethernet interface to connect to any xDSL 
modem.  You can find cheap used ones on ebay.

 I have a nice laser printer set up on my router which was installed via
 CUPS and shared via samba.  It works perfectly with my XP and 2k
 machines, but I am having trouble getting my 4.8 Desktop machine to
 print to it.  I installed the same version of CUPS on the desktop to try
 to facilitate the setup.  Right now, anytime I send a print job (print
 test page, line print), it connects, then says the printer is busy, will
 try again in 10 seconds.

 Any ideas on how to get through this?  Note:  I am not totally against
 trying a different way to configure the printer, I just am more
 familliar with CUPS than with printcap.

It's hard to tell from your message whether the printer has an internal
print server or is attached to a router which is acting as a print
server.  Either way, if the print server supports lpr/lpd, it's easy to
do with a printcap entry.  Having installed CUPS may complicate this; I
don't know what it does to existing lpr/lpd setups.

A simple printcap entry for a remote printer:

lp:\
:lp=:\
:sh:\
:mx#0:\
:rm=laser:\
:rp=raw:\
:sd=/var/spool/output/lpd/lp:\
:lf=/var/log/lpd-errs:

laser is entered in /etc/hosts as the hostname and address of the
laser printer; you could also just enter the IP address of the printer
directly in printcap.  raw is the standard queue name for HP
JetDirects; some print servers don't care about the name, some are
picky.  /var/spool/output/lpd/lp is the spool directory, which has to be
created before you can print through this queue.
