  documentStyles.push({ content: `p {font-size: 12pt !important;font-family: 'Times New Roman'!important;}` } as PdfDocumentStyle);

  //set up page format
  const pageFormat: PdfPageFormat = new PdfPageFormat();

  //indicate to display header and footer
  pageFormat.displayHeaderFooter = true;

  //style header
  const styleHeader = `font-size: 11pt !important;font-family: 'Times New Roman', Times, serif !important;
                  margin-left: 56px; margin-right: 56px;

                  color: #696969;`;

                  color: #696969;`;
  
  //set up header and footer templates with the above styles
  pageFormat.headerTemplate = new PdfBaseHeaderFooterTemplate(styleHeader, '<p>This is a header: <b>Bold Stuff</b></p>', PdfBaseHeaderFooterTemplate.EMPTY_TAG);
  pageFormat.footerTemplate = new PdfBaseHeaderFooterTemplate(styleFooter, `<b>

  const pdfTemplate = new PdfDocumentTemplate(content, pageFormat, ...documentStyles);
  const buffer = await pdfTemplate.createPdf();
