This code worked for me in angular 9, Yii2, while using mpdf

this._gService.download_post(`controller/action`, postData).pipe(takeUntil(this._unsubscribeAll)).subscribe(result => {

  const fileURL = URL.createObjectURL(result);

  // Direct print preview

  // const iframe = document.createElement('iframe');
  // iframe.style.display = 'none';
  // iframe.src = fileURL;
  // document.body.appendChild(iframe);
  // iframe.contentWindow.print();

  // Direct Download

  const fileName = 'Patient Report';
  const a = document.createElement('a');
  document.body.appendChild(a);
  a.href = fileURL;
  a.download = fileName;
  a.click();


}, error => {
   // show error message
});
