lpd printing not working for Macbook pro to windows 7

I followed the steps listed below, and had my printer on teh macbook pro working for about 1 day, now it doesn't work at all. I've uninstalled the printer and followed the steps again, still no joy.

Windows printing doesn't work either on the mac to winblows 7.

This is a windblows 7 issue whereas on XP I had no issues.

any suggestions would be much appreciated.

OS 10.6.8

Steps I followed are here:

On the Windows 7 PC

1. In Windows 7 Control Panel

2. Select "Programs and Features" pane

3. Click "Turn Windows Features on or off"

4. Turn on the LPD protocol.

5. Ensure printer(s) are shared

On the Mac

1. Start Applications/Utilities/Printer Setup Utility

2. Hold down the "Option" key and click the "More Printers" button

3. From the top menu select "Advanced"

4. From the "Device:" field select "LPD/LPR Host or Printer"

5. In the "Device URL:" lpd://PCName/PrinterShareName

6. Click the "Add" button
