Printing wirlessly, Windows 2000 to Airport and Bonjour not working

Question

My set-up is as follows: Airport Extreme with printer sharing on and my printer is listed. 5 year old iMac connected to Airport Extreme via ethernet and running 10.3.9. Printer Sharing, Personal File Sharing, Internet and Windows Sharing is on and the iMac prints fine. PowerBook is connected wirelessly with an Airport card and is running the the latest Tiger. Again, Printer Sharing, Personal File Sharing, Internet Sharing and Windows Sharing, is on and my PowerBook prints fine. BTW, I'm printing through a HP 7200.
My wife has a 3-year-old IBM Thinkpad running Windows 2000 with a wireless card installed. She can join my Airport network and connect to the internet fine. Sharing is on. I've installed the HP software and it shows up in the Printers pane and I also right clicked and turned on sharing for this specific printer. I can select it and it prints fine if I hardwire the printer to the IBM's USB port.
When I installed Bonjour and the pain for available printers comes up non are listed (my wife has several printers in her Printer pane as it is a work machine and she sometimes has to bring it to work and print. At home she usually uses her own Lexmark but I want her to be able to use my printer as the Lexmark isn't that great). I've tried everything including re-installing Bonjour (yes, even the latest Bonjour) and even the HP printer software/drivers. Nothing seems to work.
And I thought Bonjour was supposed to be "seemless"?Any ideas would be much appreciated. I've been fiddling with this thing off and on for a few months now to no avail. Thanks in advance!

Answer 1

I appreciate your suggestions but I have a slightly
more complicated wireless network: I have an iMac G5
in my home office, and my daughter has a PC with
Windows 2000 in her room with a wireless card.
Internet comes through a DSL modem in my office into
an Airport Extreme that is networked with an Airport
Express in my daughter's room. The Express is
needed to boost the wireless signal to her room.
Move the Express to a position two thirds of the way from your Office to her room.
If the signal is weak when it arrives at the Express, it can't do anything to boost if if the computer is in the same room... It won't do anything.
If you move the AX to a position where it can receive a stronger signal it can then boost that stronger signal to an area which otherwise would receive a weak signal.
An AX can not improve a weak signal by itself, it needs to recieve a strong signal to begin with, all it does is increase the prospective range of the wireless network.
You say
her
computer can recognize, using Bonjour, an HP printer
then you say
However, her computer neither sees the HP printer
Can she see or not see the printer?
I would move the AX as described and see if that makes a difference.
