<div style="display:none !important;">
  <div  id="printMe">
    <div style="width:100%;min-height:1000px;padding:10px 0;page-break-after:always;position: relative;">
       <div class="imgbox">
                  <img :src="img_url" alt="">
            </div>
    </div>
    <div style="width:100%;min-height:1000px;padding:10px 0;page-break-after:always;position: relative;">
       <div class="imgbox">

            </div>
    </div>
  </div>
</div>
</template>
<style scoped>
  .imgbox{
    text-align:center;
    width: 100%;
    height: 270mm;
}
.imgbox img{
    position: absolute;
    top: 0;
    left: 0;
    width: 100%;
    max-height: 275mm;
    display: block;
