Hello and Welcome to Just Answer...my name is ***** ***** I can help you with your Network Printer question.
In order to give you the right guidance I need to know a bit more information.
- Just to make sure, is the model number for this unit: MP 25506 as you stated above or is it: MP 2550B ?
- Is this unit already connected to a network that you might need network administrator rights? or are you connecting it in a private/home environment?
Please reply back those those questions in order to give you the best possible guidance on what to do next.
