This is an issue with the iPad3.

I have a Xerox printer and I have tried several print utilities and it always cannot find my printer after an hour or so.  If I change nothing, then reboot the iPad it find the printer again.  I went to the Apple store and the "genius" told me it was because it was not airport printer.  This is also false.  My friend brought over his airport printer and after one hour guess what.  No printers, had to reboot the iPad.

Don't go crazy, this is a bug in the iPad3.  Hopefully they will fix it soon.  Until then we will all need to reboot if we want to print.  I even tried a static IP on my wireless, no change.  Of course I already had a static IP on my printers.

The symptoms of the bug are the first web page you pull up takes 10 seconds to come up, it is at this point you know the printers will not be there. After you reboot the iPad3 the same web page comes up like lightning fast and the printers are there. Weird bug, something is going to sleep or something with the wireless. It might have to do with the encryption in the wireless as I have mine set to very high. AES

I just timed it.  It is not 1 hour.  It is around 15 minutes.  Every time it goes out it is around 15 minutes.

Every time I reboot and presto, the printers are back.

This is a weird bug.  I suggest Apple allow LPD printing to an IP and this issue will go away.  Lock the IP and the LPD into flash memory and quit trying to invent stuff that doesn't need to be invented.  The printers never disappear on my Mac computer just on this iPad 3.  My mac uses LPD and a staic IP.  LPD is UNIX stuff from the 80s and it is ROCK solid.  It is something stupid with the airport and the iPad3 bug using new protocols which are not needed to print.  It is always funny how companies get bugs when they try to reinvent something that does not need to be reinvented.  LPD printing is not broken, therefore , don't fix it, use it.
