So I am trying to connect my HP Photosmart C4780 to my network. My router is an Airport express. I know that you can connect it via USB to the back of the Express but I cannot do that due to the fact that the router is in a different part of the apartment. I am trying to connect it Wirelessly through the application that came with the Printer. I can set it up fine by USB but when the Application asks if I want to connect the printer wirelessly it doesnt pick up ANY wireless networks around me. I have tried Googling the problem and it seems that there are a lot of issues surrounding this model but none of them had my specific problem. Any suggestions?
