I contacted USR and got a prompt reply that worked fine.
N.B. - if you've been hacking around with this for a while you've likely created several tcp/ip ports under the printer properties. I had to get rid of this junk (and I rebooted for good measure as well) and then it worked just fine.
You must first set-up the printer directly to Vista computer. You will connect the printer USB cable directly to the Vista machine and install the printer with it drivers from the printer cd and after you've completed the installation, print a test page.
Once you've got it to print the test page, re-connect the printer to the router and add the printer to the Vista computer with add printer wizard.
I'm including a Word Document with a graphical view of the installation.
Here is the document
USR5461 - Windows Vista USB Printer Installation
A USB printer can be connected to the Wireless MAXg Router and used as a network printer if you are using an operating system that supports printing to an Internet Printing Protocol (IPP)-based printer. Windows Vista has built-in support for this function.
Step One: Local Printer Installation
Note: If your printer and printer software is already installed on your computer, skip to Step Two: Print Server Configuration.
Before configuring your printer on the print server, it is important to install it on your computer using the drivers provided by the printer manufacturer.
1. Plug your USB printer into one of the USB ports on your computer.
2. Install the printer by following the installation instructions included with your printer.
3. Print a test page to ensure that the printer is working properly.
Step Two: Print Server Configuration
1. Plug the thin rectangular end of the USB cable into the USB port on the Wireless MAXg Router.
2. Connect the power supply to your printer and turn your printer on.
3. Launch a Web browser. In the location or address line type 192.168.2.1 and press Enter.
Note: If you have modified your router's IP address, enter the new IP address instead of 192.168.2.1
4. When the user name and password window appears, type in the user name and the password you created. Click OK to load the router's setup page.
Note: You will not be prompted to login the first time you connect to the MAXg Router's Web User Interface. During the Setup Wizard procedure, you will be prompted to create a user name and password to log in to the router. If you create a user name and password, you will need to use these whenever you want to log in to the Wireless MAXg Router. The user name and password are case sensitive.
5. In the Device section of the Status page, look for the Printer status and Printer location information.
Write down the Printer location address. This information will be used in step 10..
Note: Perform the following steps to set up your printer. You will need to do this on every computer that is connected to your network and wants to be able to access the printer.
6. Click the Start button, then Control Panel. Under Hardware and Sound, click "Printer".
7. Click Add a printer. This will start the Windows' Add Printer Wizard
8. In the "Choose a local or network printer" window, choose Add a network, wireless or Bluetooth printer and click "Next".
9. In the "No printers were found" window, choose The printer that I want isn't listed and click "Next".
10. In the "Find a printer by name or TCP/IP address" window, choose Select a shared printer by name and enter the URL to your printer.
Note: The default URL is
http://192.168.2.1:1631/printers/My_Printer
After entering the URL, click "Next".
11. The Add Printer Wizard will then attempt to connect to your printer. If you get an error that your printer cannot be found or cannot connect, please temporarily disable any software firewall which may be blocking communications to port 1631 which is the port used by the print server. After setting up your printer, you can then opt to turn the firewall back on and make an allowance for port 1631 in it's configuration options.
12. You will now be prompted to select the manufacturer and model of your printer. If your manufacturer or model is not listed, please contact the manufacturer for drivers. After you have the proper drivers, you can continue the installation by clicking the "Have Disk" button and browsing to where the drivers are located.After selecting the manufacturer and model, click "Next".
13. In the "Type a printer name" window, give your printer a name. Check "Set as the default printer" if this is going to be the default printer. When you are done, click "Next".
14. You will now be presented with a windows stating that you've successfully set up your printer. You will see a button labeled "Print a test page". Click this button to test your printer. After the test page prints click the "Finish" button to complete the installation.
15. Your newly installed printer will now appear in the installed printers window.
