MacBook Air can't find wireless printer
My MacBook Air can't "see" my wireless printer and will only print when connected by USB. I've been through every troubleshooting suggestion the HP support site could offer and they referred me here. I don't believe it's a problem with the printer or network because I can print just fine from my phone or my husband's MacBook Air. I can't find any settings on his computer that are different than the settings on mine and we're both running iOS 10.11.4. I would welcome any advice or suggestions.
Thanks in advance!
MacBook Air, OS X El Capitan (10.11.4)
