Airprint not working after iOS 11.4.1 update - solution
After updating to 11.4.1 my iPad could no longer find an Airprint-enabled printer on my wifi network. The issue was fixed by resetting the Network Settings (Settings/General/Reset/Reset Network Seetings). Needed to sign back into the wifi network afterwards and then the printer appeared again.
iMac, macOS High Sierra (10.13.1)
