I have an HP All-in-one inkjet printer connected to an Apple Airport Extreme through the Airport's USB port. I have two Apple notebooks running OS X that are able to see and use this printer as a Rendevous printer wirelessly through the Airport. They do NOT have any trouble with Internet connectivity. Occasionally, though, the printer seems to be unavailable and not able to be seen by the Add Printer software. I can sometimes get the printer to be recognized again by going through a power down/up, disconnect the cables song and dance procedure but it is aggravating to have to do so and it does not always work.
What could the possible reasons be and steps to overcome this problem? It seems like once the printer is recognized, it should stay recognized and usable but even though there are no power failures or cables being disconnected or any other changes that would cause the printer to be lost, it gets lost anyway.
Any thoughts? Could it be a hardware failure of the Airport? Is there something that periodically re-searches for printers that might be the culprit? Any suggestions on ways to test for what is causing the problem?
