HP laserjet m1212nf - Manual (Page 245)

You are unable to print from a third-party USB card.
Cause Solution
This error occurs when the software for USB products 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 product does not appear in the Printer Setup Utility or Print & Fax list after
the driver is selected.
Cause Solution
This problem is caused by either a software or a hardware
component. Software troubleshooting
● Check that your Mac supports USB.
● Verify that your Mac operating system is Mac OS X v10.4 or
later.
● Ensure that your Mac has the appropriate USB software from
Apple.
Hardware troubleshooting
● Check that the product 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 non-powered USB hubs are
connected in a row on the chain. Disconnect all of the devices
from the chain, and then connect the cable directly to the USB
port on the host computer.
NOTE: The iMac keyboard is a non-powered USB hub.
