You are unable to print from a third-party USB card.

Cause

Solution

 

 

This error occurs when the software for USB printers is not installed.

When adding a third-party USB card, you might need the Apple USB Adapter Card Support software. The most current version of this software is available from the Apple Web site.

When connected with a USB cable, the printer does not appear in the Print Center or Printer Setup Utility after the driver is selected.

Cause

Solution

 

 

This problem is caused by either a software or a hardware component.

Software troubleshooting

●Check that your Macintosh supports USB and has the appropriate USB software from Apple.

●Verify that your Macintosh operating system is Mac OS X V10.1 or later.

Hardware troubleshooting

●Check that the printer is turned on.

●Verify that the USB cable is connected correctly.

●Check that you are using the appropriate high-speed USB cable.

●Ensure that you do not have too many USB devices drawing power from the chain. Disconnect all of the devices from the chain, and connect the cable directly to the USB port on the host computer.

●Check to see if more than two nonpowered USB hubs are connected in a row on the chain. Disconnect all of the devices from the chain and connect the cable directly to the USB port on the host computer.

NOTE The iMac keyboard is a nonpowered USB hub.
