When you are installing NiceLabel diver manually from Printers & Scanners dialog box in Control Panel, Windows prompts you with the message:
The software you are installing for this hardware: Printers - has not passed Windows logo testing to verify its compatibility with Windows.
Continuing your installation of this software may impair or destabilize the correct operation on your system either immediately or in the future. Microsoft strongly recommends that you stop this installation now and contact the hardware vendor for software that has passed Windows Logo testing.
This is a standard Windows warning message that appears always when you try to install a device driver that is not digitally signed by Microsoft. The warning does not appear only with NiceLabel divers, but also with drivers from other manufacturers.
NiceLabel drivers are Windows compliant and can be installed on Windows operating system. It is safe to continue with the installation of NiceLabel divers despite the fact they do not have Windows Logo.
Use Printer Installation Wizard (prninst.exe) that is included in NiceLabel divers installation package o disable the appearance of this warning message.
