Why don’t you try mPDF version 2.0? I used it for creating PDF a document. It works fine.
Meanwhile mPDF is at version 5.7 and it is actively maintained, in contrast to HTML2PS/HTML2PDF
But keep in mind, that the documentation can really be hard to handle. For example, take a look at this page: https://mpdf.github.io/.
Very basic tasks around html to pdf, can be done with this library, but more complex tasks will take some time reading and "understanding" the documentation.
