Do computers in a network need same service pack to share printer? -

I have a Canon MP830 and recently reformatted and now can t get my network printer to share properly. I have SP3 on the main computer hooked up to the printer and the laptop trying to access it is service pack 2. Do I need to have Service Pack 3 on both computers?

No. You just need the printer driver installed in all of them. Make sure your laptops are connected to the printer (wires are a good investment).
