I'm not intimately familiar with CUPS, but that doesn't seem right.
You should get some response.

At least it exists.

    Dave> Is not having an AuthType a good thing? A bad thing?

The AuthType directive turns on authentication and indicates what
kind.  In general this is a good thing but configuration is
complicated.  Better that it be off now.  Nor do you really need it.

Josh's advice is basically what I'd give.  Read dmesg.  Tail the
syslog, and plug the printer in and out and see what it says about the
device as the kernel notices it.
