This article provides step-by-step instructions on how to add a network printer to a computer running Windows Vista.  This example uses "LPR" protocol (stands for Line Printer Daemon) to communicate with the printer.  It's fairly straight-forward, but I just wanted to write down the steps so I didn't have to "re-learn" it every time.

1. Click on the Windows Start Button and then "Printers" 

2. Click on the "Add a Printer" menu item

3. Click the "Add a network, wireless or Bluetooth printer" option

4. Your computer might be able to discover the printer automatically, but I never had any luck with that ... so I just clicked on "The printer that I want isn't listed" option.

5. Choose the "Add a printer using a TCP/IP address or hostname" option

6. Find the IP Address, TCP Port, and LPR Queue Name for the printer you want to install.  I am using D-Link's DPR-1260 RangeBooster G Multifunction Print Server to host the printers on my network.  However, these instructions aren't necessarily specific to this print server.  You should just find the screen on your print server that provides info like the stuff highlighted in the screenshot below.  These values will be used in the next few steps. 

NOTE: Although my extremely frustrating experience with D-Link's WBR-1310 Wireless G Router has completely shattered any confidence I had in D-Link, I have to admit I haven't had many problems at all with this wireless print server.  It hosts up to four USB printers, and even allows me to still use the scanner on my HP PSC 2100 All-In-One ... although since that particular printer isn't in the compatible multifunction printers list I could only get it to work using "Scan" tab in the D-Link interface shown below.

7. Type the IP Address and Port name in the wizard.

8. Choose the "Custom" option, and then click the "Settings" button.

9.  Set the protocol to be "LPR", and then enter the LPR Queue Name we found in Step 6.

10. Choose the appropriate printer driver.

11. Give the printer a friendly name.

12. Windows starts installing the printer on the machine.  Wait for it to finish and click Next.

13.  Choose whether you would like to share the printer with other computers or not.

14.  SUCCESS!!!
