Creating multipage pdf from html - text is being cutting off

    // assign the print formatter to the print page renderer
    let renderer = UIPrintPageRenderer()
    renderer.addPrintFormatter(printFormatter, startingAtPageAt: 0)

    // assign paperRect and printableRect values
    let page = CGRect(x: 0, y: 0, width: 595.2, height: 841.8) // A4, 72 dpi
    renderer.setValue(page, forKey: "paperRect")
    renderer.setValue(page, forKey: "printableRect")

    // create pdf context and draw each page
    let pdfData = NSMutableData()
    UIGraphicsBeginPDFContextToData(pdfData, .zero, nil)

    for i in 0..<renderer.numberOfPages {
      UIGraphicsBeginPDFPage()
      renderer.drawPage(at: i, in: UIGraphicsGetPDFContextBounds())
    }

    UIGraphicsEndPDFContext();

    // save data to a pdf file and return
    guard nil != (try? pdfData.write(to: outputURL, options: .atomic))
      else { fatalError("Error writing PDF data to file.") }

    return pdfData as Data
