Strange; I just created an alias on my PC, told cups to listen on my main IP, and it did...
eth0 = 192.168.16.23
eth0:0 = 192.168.16.40
# grep Listen /etc/cups/cupsd.conf
# netstat -nltp | grep cupsd
tcp 0 0 192.168.16.23:631 0.0.0.0:* LISTEN 18733/cupsd
tcp 0 0 127.0.0.1:631 0.0.0.0:* LISTEN 18733/cupsd
$ telnet 192.168.16.40 631
telnet: connect to address 192.168.16.40: Connection refused
telnet: Unable to connect to remote host: Connection refused
Guess you restarted cupsd... right?
