When installing Loftware driver, a dialog box displays a message that the driver did not pass Windows Logo testing


When you are installing Loftware driver 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 Loftware drivers, but also with drivers from other manufacturers.

Loftware drivers are Windows compliant and can be installed on the Windows operating system. It is safe to continue with the installation of  Loftware drivers despite the fact they do not have Windows Logo.

Use the Printer Installation Wizard (prninst.exe) that is included in Loftware drivers installation package, or disable the appearance of this warning message.
