I've used the solution from this other question (in English):

public string RenderRazorViewToString(string viewName, object model)
{
  ViewData.Model = model;
  using (var sw = new StringWriter())
  {
    var viewResult = ViewEngines.Engines.FindPartialView(ControllerContext,
                                                             viewName);
    var viewContext = new ViewContext(ControllerContext, viewResult.View,
                                 ViewData, TempData, sw);
    viewResult.View.Render(viewContext, sw);
    viewResult.ViewEngine.ReleaseView(ControllerContext, viewResult.View);
    return sw.GetStringBuilder().ToString();
  }
}


public ActionResult RenderViewToString()
{
    var model = new MeuModelo()
    {
        Nome = "William John",
        Endereco = "123, rue des Canadiens",
        Telefone = "(555) 555-7777"
    };

    string html = RenderViewToString(
            "~/views/Etiqueta.cshtml",
            model);


    CreatePdf(html);

    return View();
}

How it works:

The ViewEngines.Engines.FindPartialView Method (if you want to render a View, use the FindView method) creates an instance of your partialview in viewResult

An instance of ViewContext is created. This is where the model and tempdata are provided to the View.

The Render method renders HTML rendering and uses the StringWriter to create a String Builder that will receive the Render result.
