The below solution is working on all the browsers especially IE6. The response time in Firefox is 10 sec, but in IE6 it is 2 min 30 sec.

$('#printall1').click(function() {
    $('#fourElementsonly').empty();
    var cleartable = 0;
    var maxlimit = 0;
    var presentarraycount = 0;

    $.post("/PortalUserReport/getjunkdata", null, function(response, status) {
        var report = eval(response);// we have 6000 records in the report now
        var totalRecordsCount = report.length; // count = 6000 
        var totalRecordsCountfortheLoop = totalRecordsCount;
        var arraycount = Math.ceil(totalRecordsCount / 1000);
        var reports = new Array(arraycount); // reports[6]
        for (var i = 0; i < arraycount; i++) {
            $('#fourElementsonly').append('');
        }
        reports[presentarraycount] = "";
        $.each(report, function(x) {
            if (cleartable == 0) {
                for (var i = 0; i < arraycount; i++) {
                    $('#Portal_User_elements' + i).empty(); 
                }
                cleartable++;
            }

            if (recordnumber <= totalRecordsCountfortheLoop) {
                reports[presentarraycount] += "  " + recordnumber + "     Name :" + report[x].FirstName + "  UserName :" + report[x].UserName + "   Company : " + report[x].Company + "  ";
                reports[presentarraycount] += "    Registration Date :  " + report[x].ActiveDate + "   User CN : " + report[x].UserCN + "   Status: " + report[x].Status + "    ";
                reports[presentarraycount] += "    User Privilege : " + report[x].Privileges + "    ";
                maxlimit++;
                if (maxlimit == 1000) {
                    presentarraycount++;
                    reports[presentarraycount] = "";
                    maxlimit = 0;
                }
            }
            recordnumber++;
        });

        for (var i = 0; i < arraycount; i++) {
            $('#Portal_User_elements' + i).append(reports[i]);
        }
    });
});
