I finally got my html2pdf to work showing my web page just how I want it in the pdf(Any other size was not showing right so I kept adjusting the format size until it all fit properly), and the end result is exactly what I want it to look like... EXCEPT even though my aspect ratio is correct for a landscape, it is still using a very large image and the pdf is not standard letter size (Or a4 for that matter), it is the size I set. This makes for a larger pdf than necessary and does not print well unless we adjust it for the printer. I basically want this exact image just converted to a a4 or letter size to make a smaller pdf. If I don't use the size I set though things are cut off.

Anyway to take this pdf that is generated and resize to be an a4 size(Still fitting the image on it). Everything I try is not working, and I feel like I am missing something simple.

 const el = document.getElementById("test);
    var opt = {
      margin: [10, 10, 10, 10],
      filename: label,
      image: { type: "jpeg", quality: 0.98 },
      //pagebreak: { mode: ["avoid-all", "css"], after: ".newPage" },
      pagebreak: {
        mode: ["css"],
        avoid: ["tr"],
        //    mode: ["legacy"],
        after: ".newPage",
        before: ".newPrior"
      },
      /*pagebreak: {
      before: ".newPage",
      avoid: ["h2", "tr", "h3", "h4", ".field"]
    },*/
      html2canvas: {
        scale: 2,
        logging: true,
        dpi: 192,
        letterRendering: true
      },
      jsPDF: {
        unit: "mm",
        format: [463, 600],
        orientation: "landscape"
      }
    };

   
      var doc = html2pdf()
     
        .from(el)
        .set(opt)
        .toContainer()
        .toCanvas()
        .toImg()
        .toPdf()
         .save()
