title: HTML page to PDF with automatic height
body: <p>I have an HTML page that I need to convert to PDF with C#, and I can't find how to make sure my PDF have exactly a width of 80mm and an automatic height (depending of content of the page). The HTML file is a receipt.</p>
  
  <p>I have tried many libraries, but can't find the optimal solution.</p>
  
  <p>Thanks.</p>
