可能的解決方案

var ping = require('ping'); 
var hosts = ['10.0.0.2','10.0.0.3']; <--- printer A and B addresses 
hosts.forEach(function(host){ 
    ping.sys.probe(host, function(isAlive){ 
     var msg = isAlive ? 'host ' + host + ' is connected' : 'host ' + host + ' is not connected'; 
     console.log(msg); 
    }); 
});
