I know that this forum has British readers, so here’s an observation about the BT Smart Hub, the very common router British Telecom supplies with their broadband packages.
Brand-new M1 iMac running Ventura.
Installing an EPSON ET2850 ran into a deadlock, the printer was recognised over WiFi, but installation ended with an error message. Switching off IPP (or rather IPPS) over https:// on the printer made the reactions much faster, but still ended in an error.
Printing from iOS worked already.
We switched the BT Smart Hub to a lower spec WiFi mode.
In Mode 2 it works on the Mac but not with iOS.
In Mode 3 it works with iOS, but not the Mac.
We ended with connecting the Mac on an Ethernet cable, instead of WiFi.
During the installation we saw a message that “An update for AirPrint is required. Yes/No.” I’m not sure if this comes from macOS or some EPSON function and I couldn’t find out what it is. We did this, but it didn’t improve the situation.
Never a dull moment with BT’s hardware, heavily advertised as latest and greatest, but in reality not anyway near that.
