Você pode fazer uma de duas coisas:
-
Rodar o seguinte programa vbscript com “cscript listprinters.vbs” . Veja que ele tem uma opção para redirecionar a saída para um arquivo (para consultar as opções, rode com “cscript listprinters.vbs /?”. (Esse programa é do Windows 2000 Resource Kit, deve funcionar em Windows 2000, XP, 2003 mas não tenho certeza quanto ao Windows Vista. Não deve funcionar em um Windows 9X ou ME). Note também que, se as permissões adequadas forem dadas, esse programa pode consultar as impressoras instaladas em outras máquinas também. Teste esse programa na sua rede.
-
Pegar a DLL “prnadmin.dll” no Windows 2003 Resource Kit, ler o documento “prnadmin.doc” que vem com ele, e, usando Jacob, ( http://sourceforge.net/projects/jacob-project/ ) chamar os métodos da DLL prnadmin.dll (que é uma DLL que deve ser registrada). Leia o manual atentamente para ver o que ela pode fazer.
Abaixo segue o listprinters.vbs.
