function createPdf(
  docDefinition: TDocumentDefinitions,
  tableLayouts?: { [name: string]: CustomTableLayout },
  fonts?: TFontDictionary
): Promise<Buffer> {
  return new Promise((resolve, reject) => {
    const printer = new PdfPrinter(fonts ?? {});
    const pdfDoc = printer.createPdfKitDocument(docDefinition, { tableLayouts });
    const chunks: Uint8Array[] = [];
    pdfDoc.on('data', (chunk: Uint8Array) => chunks.push(chunk));
    pdfDoc.on('end', () => resolve(Buffer.concat(chunks)));
    pdfDoc.on('error', reject);
    pdfDoc.end();
  });
}
