Windows 10 upgrade problem
Currently (Aug 2017) IDP's printers don't have certified signed drivers from Microsoft. We will be launching our new certified driver within in the next few months.
If you wish to install an IDP Printer and are using Windows10 or will be upgrading to Windows10, that operating system requires certified drivers as a default setting.
Once you've completed this process, you'll be able to install the current IDP SMART Printer Driver.
