Hello forum! I just bought a HP 6510 photo smart printer. The first day I had it was was able to pick up the wifi signal and print through the Android HP ap on my galaxy s2 and transformer prime. A friend of mine also has an hp wireless printer. I was able to find his printer and connect directly to it with both my phone and tablet until today.......Now both my table and phone will no longer pick up his printer or mine. They dont even show up when I scan for wifi devices. I am having a hard time figuring out how it worked on both his and mine until today. Finding the printers wifi signal on both printers with both devices and now not being able to find either blows my mind!!!!!! Thanks in advance for any help!
