HP Color LaserJet 4730 Multifunction Printer series - Manual (Page 339)

When connected with a USB cable, the printer does not appear in the Desktop Printer Utility or the Apple System Profiler after the
driver is selected.
Cause Solution
This problem is caused by either a software or hardware component. Software troubleshooting
● Check that your Macintosh supports USB.
● Verify that your Macintosh operating system is Mac OS v9.1 or
later.
● Ensure that your Macintosh has the appropriate USB software
from Apple.
NOTE The iMac and Blue G3 desktop Macintosh systems
meet all of the requirements to connect to a USB device.
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.
