Connecting the Cable
You can connect the USB/Parallel Adapter directly to a USB port on your iMac or to a USB hub connected to a port on the iMac. If you have any printing problems when the printer is connected via a USB hub, try connecting the printer directly to the USB port on the iMac instead.
1To connect the adapter to the USB port on the side of the iMac, first open the port door. Hold the adapter’s USB connector so the 
icon faces up and connect it to the available USB port.
