There are many .NET solutions for converting html to pdf but these can be quite expensive. If the pdf is not going to be more than 10 pages then this is a free option:
Free .NET PDF Component - Developing PDF in C#, VB.NET, ASP.NET | Spire.PDF
How to convert HTML into PDF in C#, VB.NET
I have used it in the past and it works with Progress, although I have never tried the html to pdf feature.
