A little help.... When I found out the iPad could print wirelessly, I set my home network to take advantage of this feature. I have an airport extreme router, and of course, the ipad2. The new printer, a hp photosmart plus B210 worked perfectly at first from the iPad as it is designed to work with AirPrint. I also set it up to print wirelessly from any computer within my wifi network. Any computer, laptop or wired works fine with the new hp printer. My only problem is that after only one day on the ipad2, when trying to print a document or picture, the printer shows up in the print menu but now after a while the message comes up, "printer offline". It sees the printer but will not print to it. Of course, the printer is on, and everything appears normal except it does not print. Note that the AirPrint did work for one day and have not changed anything since. I tried rebooting the iPad, unplugged the printer to reset, and checked any settings I could see. The only thing I could not access was the firewall settings of the airport extreme. I don't know if that is relevant. Maybe someone knows of a thread or suggestions. I am thinking I am not the only one with this issue.
