configuration meets its needs.

The computer emits a loud, high-pitched noise.

This is feedback between the microphone and the speakers. It
occurs in any sound system when input from a microphone is fed to
the speakers and the speaker volume is too loud. Adjust the volume
control.
Printer problems
This section lists some of the most common printer problems.

The printer will not print.

Check that the printer is connected to a working power outlet,
turned on and ready (on line).
Check that the printer has plenty of paper. Some printers will not
start printing when there are just two or three sheets of paper left in
the tray.
Make sure the printer cable is firmly attached to the computer and
the printer, or the wireless connection is good.
Run the printer’s self-test to check for any problem with the printer
itself.
