    Problem:
    Have HP printer that power adapter appears to have died.
    When tested it does not produce the required 18 volts.
    A friend has a power adapter that has similar specs but is
    slightly different. If I use my friends power supply adapter do
    I run the risk of further damaging my printer even for a short test
    to make certain the power supply IS the real problem?
    Friends power supply module -- 100-240VAC input, 50/60Hz, 1.0A, 76VA,
    requires separate AC power cord - 18VDC output, 2.23A, 40 watts

    My Power supply module-- - 100-240VAC input, 50/60Hz, 1.0A max, 82-111VA,
    requires separate AC power cord - 18VDC output, 2.23A, 45 watt



    Thanks

    That should be fine , that is if your printer has not caused your PSU to
    fail. the wattage is give by Volts x Amps

    18 X 2.23 = 40.14 Watts at full load

    Should be fine. Make sure the plug polarity is the same.
    You can do this with a simple VOM.
