Problem porting UNIDRV printer driver to 64 bit RRS feed

  • Question

  • Hi, years ago i've developed a UNIDRV based printer driver that's working fine.

    Now we have recompiled the source code to 64 bit, updated the INF files, installation tool and so on and it installs fine on x64 systems.

    The problem is that this driver works only when printing from 64 bit apps, if i try to print from 32 bit apps a popup says

    "cannot start printer document"


    " a required resource is missing"

    What could be wrong?

    Please help
