I am using the ngx-extended-pdf-viewer in angular 8 for showing a pdf in a modal, it shows pdf properly but when I'm clicking on the print button it just opening the last page of pdf for print view.

this is my code: 

```
<ngx-extended-pdf-viewer
   [showBookmarkButton]="false"
   [showDownloadButton]="false"
   [showOpenFileButton]="false"
   [src]="pdfUrl"
   [useBrowserLocale]="true"
   height="80vh"
></ngx-extended-pdf-viewer>

```
