PHP：ajax表单提交然后只有打印的结果

Question

I am trying to ajax submit PHP form, it's working fine. Now whatever the result coming from PHP is getting stored in div. I want that result to print.

Here is code,

        <label>Customer. :</label>
                      <select type="text" class="form-control required" id="customer"  name="customer" onChange="get_part(this)">               

                      <option value="">Select Customer </option>
                    <?php 
                    foreach($customer_data as $ss){
                         ?>
                         <option value="<?php echo $ss['customer_id'] ;?>"
                    <?php if($edit_data!=NULL && $edit_data['customer']== $ss['customer_id']){echo "selected=selected";}?>><?php echo $ss['name'] ;?>
                       </option>
                    <?php   
                        }
                    ?>

                    </select>
                    </div>

                   <div class="col-lg-10 col-xs-4 form-group">
                      <label>Part no. :</label>
                      <select type="text" class="form-control required" id="part"  name="part" onChange="get_lotno(this)">               

                      <option value="">Select Part no</option>
                    <?php 
                    foreach($parts_data as $pp){
                         ?>
                         <option value="<?php echo $pp['part_id'] ;?>"
                    <?php if($edit_data!=NULL && $edit_data['part']== $pp['part_id']){echo "selected=selected";}?>><?php echo $pp['part_no'] ;?>
                       </option>
                    <?php   
                        }
                    ?>

                    </select>
                    </div>
                  <div class="col-lg-10 col-xs-4 form-group">
                 <label>Lot No. :</label>
                <select type="text" class="form-control required" id="order_id"  name="order_id" onChange="get_lotdetails(this)">               

                      <option value="">Select Lot No</option>

                    </select>

     <script type="text/javascript">
      $(function () {

       $("#form").validate({
      rules: {
          customer: {required: true},
          part: {required: true}
      },
      submitHandler: function(form) {
            $.ajax({

            cache: false,
            async:false,
            beforeSend : function ()
            {
                $("#submit").addClass("disabled");
                $("#table_div").html('<div align="center"><img src="<?=base_url()?>admindata/dist/img/table_loader.GIF"></div>');
            },
            success: function (data) {

            $("#ajax_loader").hide();

                $("#table_div").html(data);

                $("#lotremqnty").val($("#rem_lot_qty").val());
                $("#submit").removeClass("disabled");


        }); 
      });

On success tabular format content comes for label printing.

Anybody can help me with label printing through PHP.

Label Printer:Toshiba B-EV4T

thanks in advance

Answer 1

Use php_printer() for label printing, you have to do trial n error to align properly

e.g

   $your_printer_name = "TEC B-EV4 (203 dpi)";
        printer_start_doc($handle, "My Document");
    printer_start_page($handle);
    printer_set_option($handle, PRINTER_RESOLUTION_X, "text");
    //  printer_set_option($handle, PRINTER_MODE, "text");
    //  printer_set_option($handle, PRINTER_TEXT_ALIGN, PRINTER_TA_CENTER);
    //  printe_write($handle, "UNI-TECH Automation Pvt.Ltd. 
". $part_no.$sr_no.$result.$date.$time.$operator."
". $part_no_val.$sr_no_val.$result_val.$date_val.$time_val.$operator_val,1,1);

        $font_face = "Draft Condensed";
        $font_height =24;
        $font_width = 12;
    $font=printer_create_font($font_face,$font_height,$font_width,PRINTER_FW_HEAVY,false,false,false,0);
    printer_select_font($handle,$font);
        printer_delete_font($font);

        $font=printer_create_font($font_face,$font_height,$font_width,PRINTER_FW_BOLD,false,false,false,0);
    printer_select_font($handle,$font);
        printer_draw_text($handle,$part_no,5,35);
        printer_draw_text($handle,$sr_no,225,35);
        printer_draw_text($handle,$result,325,35);
        printer_draw_text($handle,$date,415,35);
        printer_draw_text($handle,$time,530,35);



        printer_delete_font($font);
            $font=printer_create_font($font_face,$font_height,$font_width,PRINTER_FW_BOLD,false,false,false,0);
    printer_select_font($handle,$font);
    //  printer_draw_text($handle,$part_no_val.$sr_no_val.$result_val.$date_val.$time_val,5,140);

        printer_draw_text($handle,$part_no_val,5,70);
        printer_draw_text($handle,$sr_no_val,225,70);
        printer_draw_text($handle,$result_val,335,70);
        printer_draw_text($handle,$date_val,415,70);
        printer_draw_text($handle,$time_val,530,70);

            printer_delete_font($font);

            $pen = printer_create_pen(PRINTER_PEN_SOLID,4, "000000");
    printer_select_pen($handle, $pen);
            printer_draw_line($handle, 2, 2, 605, 2);
            printer_draw_line($handle, 2, 2, 2,100 );
            printer_draw_line($handle, 2, 30, 605, 30);
            printer_draw_line($handle, 2, 60, 605, 60);
            printer_draw_line($handle, 2, 100, 605, 100);
            printer_draw_line($handle, 605, 2, 605, 100);
            printer_delete_pen($pen);


            $this->load->library('phpqrcode/ciqrcode');

    //here loop through your pdf file and print the line by line or else get the entire content inside the string at once and print



        printer_end_page($handle);
