Como encontrar impressoras não usadas no Windows (ou a última vez que uma impressora foi usada)?

Question

Estamos procurando uma maneira de encontrar impressoras não usadas no Windows (Windows 7 / Server 2008 e posterior).

Testamos este VBScript Como: Listar todos os drivers de impressora não usados e, embora no sistema são impressoras não utilizadas, não obteve resultados.
