Solution with modular design

Here is a solution using modular design pattern: 

(function() {
  var recordPrinter = {
    // Init method for controlling the printer methods
    init: function() {
      var answer = prompt("Use 'print' to print all records, or 'search' to find specific student.").toLowerCase();
      if (answer === "print") {
        this.printRecords(students);
      } else if (answer === "search") {
        this.searchRecords(students);
      }
    },
    // Method for printing records
    printRecords: function(array) {
      var container = document.getElementById("output");
      for (var i=0, j=array.length; i<j; i++) {
        for (var prop in array[i]) {
          container.innerHTML += "<strong>" + prop + ":</strong> " + array[i][prop];
          container.innerHTML += "<br>";
        }
        container.innerHTML += "<br>";
      }
      return container;
    },
    // Method for searching records
    searchRecords: function(array) {
      var name = prompt("What name do you want to search?");
      var container = document.getElementById("output");
      for (var i=0, j=array.length; i<j; i++) {
        console.log(array[i].name);
        if (array[i].name === name) {
          for (var prop in array[i]) {
            container.innerHTML += "<strong>" + prop + ":</strong> " + array[i][prop];
            container.innerHTML += "<br>";
          }
        }
      }
      return container;
    }
  };
  // Automatic initialization of recordPrinter obejct's init method
  recordPrinter.init();
})();
