It *should*. CUPS 1.2.x still supports the IPP_PORT variable.

*However*, CUPS 1.2.x defaults for local communication to take place
over a Unix domain socket (not TCP/IP loopback). If your cupsd.conf
includes a "Listen /path/to/some/sockfile.sock" directive, cupsd upon 
startup reads this and creates the socket file as needed, using it 
for local communication.

Does it help if you disable the domain socket support ? (Just delete 
or comment out the line with the socket file, and keep one of the 

  Listen 127.0.0.1:631
  Listen 192.168.54.234:631
  Port 631

lines intact as needed for your IP range.)

If this helps, you can try the next thing: keep the "Listen ...sock"
line, but make sure it appears *after* the "Listen  ....:631" line(s).

Don't forget to restart cupsd after each change to the cupsd.conf.

Firefox and OpenOffice (at least in older versions) do not know at
all about IPP, nor about CUPS. They look for an /etc/printcap file
to list available printers. You should make CUPS to create such
a file with a directive of

 Printcap /etc/printcap

Does this help?
