Why HP Officejet Pro 8100 Printer connects only with Bonjour?
MacBook Pro with MAC OS Big Sir v11.4:
After Big Sir update printer would not connect with laptop via ethernet cord or wirelessly. Search seemed to indicate printer too old for latest OS update or via AirPrint. Finally, by accident, I connected wirelessly (reset modem) with Bonjour (System preferences>printers & scanners box). If printer shows a wireless connection, select add & a 2nd page opens. Wait, then Officejet Pro 8100; Bonjour; AirPrint by use row. I'm able to use printer until I put notebook to sleep / shutdown. Then must do same process all over again when restarting laptop. The previous printer won't work so I delete it (-).
Not sure why ethernet cable from printer to laptop won't work or why AirPrint does????
MacBook Pro 13″, macOS 11.4
