The laptops are running Windows, right?
If so, not a pro, but they're showing you the driver, they can't find the printer any more than the iPad can.
If the printer claims it's on a network, perhaps it's on some other network? For reasons that may be forever shrouded in mystery or because someone reset something at some point the printer joined a neighbor's wifi.
If you've already power-cycled the printer but not the router resetting the router is absolutely the next thing to try.
If You still have the problem see if the printer's menus let you go through network set up and reselect the wifi it's attached to. Alternately, turn off it's networking altogether, restart, and when it comes up help it find your network.
Last resort, have everyone within 1.25 km of your location shut down their wifi but leave yours up, then power cycle the printer. Ha, ha, that was a joke. It'd probable work, but it was a joke.
