I have a 2002 Dell Inspiron 8200 Laptop and recently purchased a HP Photosmart C6180 All-in-One printer which I intend to use wireless.  Router is a Dell 1184 Model WX-6215D and computer has a 802.11 1180PC Wireless,MiniPCI network card. 

My problem is that I can send documents, pictures etc to the printer but I cannot scan a picture/document from the printer to the computer.  The error message is always " The scan cannot be performed because another program or computer is using the networked device.  Try again."  The Windows XP is Home Edition and network only has the one computer and one printer.  I've spent approx 3 hours on the phone with HP Technicians and numerous emails trying to solve the problem.  The HP software has been removed and reinstalled twice since the initial installation.  If anyone can provide some insight into a possible solution it would be greatly appreciated.  Thanks
