M251n HP LEDM driver cannot be installed on Windows 2008R2

Hello everyone,

We're trying to setup the M251n printer with USB connection on a Windows 2008R2 Server Standard Edt.

We cannot find drivers for this specific O/S version, only for Windows 2008 Server, Win7 or Win8 (64-bit).

The drivers seem to install correctly but in the task manager the "HP LEDM" stays with a yellow warning and the printer that is created also has a yellow warning icon.

Can someone help me on what this HP LEDM is exactly and how perhaps we could successfully install the printer?

BRgds,

Pavlos
