Printer access denied on network

Hello

I hope you can help after 3 full solid days trying to remedy this I have come to you hoping you can help.

I had a home network up and running smoothly until I had to put back my main home computer to factory settings.

I have now set up the home network which is the main home computer with a printer attached by cable the AIO 926.  A laptop and PC running on XP are working fine and i am able to print from these. I have 2 other laptops Inspiron 1525 running on vista which are on the network and can go online but just cannot get to print.

Looking at other posts I have tried the cleanup patch and reinstalled the 32 bit vista driver but all to no avail. I have tried adding the printer on a local port and through the network and have now come to the end of the road.

Please Please help.

It always tells me it is unable to connect or windows cannot connect to the printer access denied.

Thanks
