    Dymo Labelwriter 450 has stopped working


    This has been working perfectly until today when the print jobs just get stuck in the print queue. Further investigation suggests that the USB connection may not be working, in Device Manager the USB controllers list contains an entry Unknown USB Device (Device Descriptor Request Failed) with an error exclamation on it.

    I have tried uninstalling and reinstalling the software - no luck.

    The form feed button on the front of the printer is not working although the blue LED illuminates normally.

    Any ideas on how to fix this appreciated.

    :)

    Dymo labelwriter 450

    I was using my labelwriter, and suddenly stopped working. I get this Error: Cannot create instance of 'MainWindow' defined in assembly 'DYMO,DLS, Version=8.5.3.1889, Culture=neutral, PublicKeyToken=5426002a38745af9', Exception has been thrown by the target
    of an invocation. Error in markup file 'DYMO,DLS; component/MainWindow.xaml'.

    Uninstalled, tried to re install and can´t. What's wrong. How do I fix it?

    Dymo LabelWriter 450

    I have followed instructions for Dymo to install the LabelWriter 450. I cannot get it to work. I get an unknown device message.

    I have uninstalled and reinstalled this printer 3 times to no avail. I have a USB3.0 superspeed hub and had my desktop printer connected to this and an old Seiko label printer connected. Everything worked fine until the Windows 10 upgrade now nothing works
    in this hub nor will the label printer work connected to my cpu. Get same message, unknown device

    Help
