OK.
Feel like going the the command line?
Open Konsole (More Applications > Terminals).
First, we need to get your PC's IP address (because we believe the PC and the printer are on the same subnet):
ifconfig
This should get you something like the following:
[jpaglia@grendel ~]$ /sbin/ifconfig

We're interested in the "inet addr" portion (bolded, above).
The assumption is that you're using a 255.255.255.0 subnet. That means that only the last number changes for devices on the same network subnat (your wireless, in this case). My example shows
192.168.0.12, so we want to focus on the
192.168.0 portion.
Now, we need to run
nmap to scan the network (I don't recall if
nmap was included in the CD/DVD, so you might need to install it via Synaptic).
The following command should now be used:
nmap 192.168.0.1-254 | grep open -4
Depending on your results from the first command, you might have to change the
192.168.0 portion to whatever is relevant to your network.
Your results will vary from mine, but here's an example:
[jpaglia@grendel ~]$ nmap 192.168.0.1-254 | grep open -4

I
highlighted some of the values you should be looking for...
192.168.0.10 is my printer, and there it is!
Depending on the number of devices on your network, the results may be longer or shorter, but it should get you started.
