How to find or set printer IP address for wireless?

I just got a Brother HL2270-DW laser printer and I cannot figure out how
to get it installed as a wireless printer on my network.

After much searching on the 'net, I found this:

http://welcome.solutions.brother.com/bsc/public_s/id/linux/en/faq_prn.html#f00104

and followed it to the letter, until it came to a point where the
following appeared:

dpkg -x hl2270dwlpr-2.1.0-1.i386.deb /
dpkg -x cupswrapperHL2270DW-2.0.4-2.i386.deb /
dpkg-deb: building package `hl2270dwlpr' in `hl
dpkg -b ./brother_driver_packdir hl2270dwlpr-2.
dpkg-deb: building package `cupswrapperhl2270dw' in
`cupswrapperHL2270DW-2.0.4-2a.i386.deb'.
dpkg -b ./brother_driver_packdir cupswrapperHL2270DW-2.0.4-2a.i

Will you specify the Device URI? [Y/n] ->Y

0: socket
1: http
2: ipps
3: ipp
4: lpd
5: https
6: beh
7: smb
8: hp
9: dnssd://Canon%20MX430%20series._printer._tcp.local/
10: dnssd://Canon%20MX430%20series._ipp._tcp.local/
11: hpfax
12 (I): Specify IP address.
13 (A): Auto. (usb://dev/usblp0)

select the number of destination Device URI. ->

But now what?  None of the 13 numbered options seem applicable,
and I have no idea how to find or set a specific IP address.

So where do I go from here?
