Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
Unfortunately there are no dock parts available for this printer at this point. It is a 2008 model camera so all parts and support for it are long discontinued.
It is possible to use with your computer via just a simple usb cable however, a dock is not required. Would you like me to help you with getting the usb cord?
