I uninstalled the Netgear software on the PC  you don't need it and it only slows stuff down. The only reason you would want that software is if you can't do the alternate method.

Here's the tip:
1. you have to know the address your router assigned to the ps121. you use your web browser to configure the ps121 to a fixed IP address. you will need to read the manual for the password to log in to the server.
2. you will have to create a TCP/IP printer port, either by adding a new network printer, or by adding a new port to your existing printer.

It took about 5 minutes per pc to set up and run a test print with this method.

For the Vista Laptop that connected via wireless to the WLAN, I used the add printer function, selected network printer, typed in the IP address, and Vista found the correct printer driver and installed it.
