Background Story: I accidentally ripped out the Ethernet port of my wife’s iBookG4. So, I purchased the USB 2.0 -> Ethernet 2.0 Adapter (AX88772A), so she can still surf the Internet via our Ethernet router. (She refuses to use Airport).
Connecting to the Internet: Success.
Printing to the Shared USB EPSON RX680 Printer (that’s shared from a different Mac on the network): Failure.
It will see the printer as a shared printer, but the drivers, etc., to choose from in the Print Utility are all greyed out on her iBookG4, ever since we’ve used this Plugable adapter. (My MacBook, still on regular Ethernet, sees and prints to the shared USB printer just fine). It will try to print when the job makes it to the shared USB printer’s Mac, then it will stop all the jobs with no printing done. (Probably because I can’t choose the drivers on her iBookG4 - all greyed out).
