    Hello friend,


    I have the solution for your problem just do as i say.........

    1.Firstly check that all the cables are connected or not.

    2.This may be the problem of the no power connection.

    3.If that is not your problem then the problem is ith the drivers.

    4.So you try to re-install the drivers of the printer.

    5.Or you update the present drivers.

    All the best.................

    Dear Friend...

    It is the most common issue which is complain by so many MacBook user.
    After upgradation of your Mac OS, none of your device apps and software's are longer to use further because their install files has been deleted via upgradation from your C-Drive or the drive where the OS is installed.



    To fix this issue, you need to insert the printer drivers disc into MacBook disc drive and start installing the set-up.
    Once the installation has been finished, you need connect your printer again, plug all the cable and wires and start using your printer.

    Thank you...

    The problem might be occurring because:-

    -There might not be divers installed properly.

    -Needed drivers might be missing.

    -The connection might be loose.

    -There might be some hardware issue with the printer.

    The solution to your problem is:-

    -Remove all the connections.

    -Make a fresh connection.

    -Make sure the connection is not loose.

    -Restart your system.

    -If the issue is not resolved,check for the latest drivers.

    -Download and install the latest drivers from the hp store.

    -Restart the system.

    -If still problem persists,then there must be some hardware issue.

    -In such cases,go to the hp service center with your printer.

    Hope your problem will be solved.
