Hello. We bought the HP Photosmart 7510 printer specifically so that I can print from my iPad2 and iPhone 4s. It was definitely working a few days ago and now the iPad2 and iPhone 4s will no longer detect the printer. It's printing fine from my MacBook Pro laptop, so I'm not sure what to do. I rebooted and checked that all my iOS devices were all connected to our wireless. No go. I hope someone can help me.
