Only access the hierarchy in which the data is found.

Notice that itensPedido is an array , inside it has a impressoraPedido object and inside this object it has what you need.

 
var obj = {  
   "empresa":"testes",
   "itensPedido":[  
      {  
         "impressoraPedido":{  
            "persistenceId":2,
            "persistenceId_string":"2",
            "persistenceVersion":0,
            "persistenceVersion_string":"0",
            "codigoImpressora":"2",
            "codEmpresa":3,
            "patrimonio":"1327",
            "modeloImpressora":"T644",
            "setorinstalacao":"Depósito peças"
         },
         "suprimentoPedido":{  
            "persistenceId":3,
            "persistenceId_string":"3",
            "persistenceVersion":0,
            "persistenceVersion_string":"0",
            "codigoModeloImpressora":"2",
            "codigoModeloSuprimento":2,
            "nomeSuprimento":"TONER LEXMARK T644",
            "codModeloSuprimento":"64418XL"
         },
         "quantidadePedido":1
      }
   ]
};

console.log(obj.itensPedido[0].impressoraPedido.codigoImpressora);

// Ou, se tiver mais de um item no array

for(let itemPedido of obj.itensPedido) {
    console.log(itemPedido.impressoraPedido.codigoImpressora);
}
