Probably because the desktop is only listening on the lo intenface.
Run "netstat -ntl | grep 631" to verify this.

For example, my print server is listening on all interfaces, and
hence the output looks like this:

	tcp    0      0 0.0.0.0:631           0.0.0.0:*          LISTEN      

My desktop, however, is only listening on lo, hence the 127.0.0.1:

	tcp    0      0 127.0.0.1:631         0.0.0.0:*          LISTEN      

The confusing thing is that your cupsd.conf appears to look OK, and
I would expect it to be listening on all interfaces. I'd guess the
next step would be to break out tcpdump and start checking what's
coming in over the wire.
