Thanks for getting back to us. It’s possible you may find a (third-party) tool which allows you to convert direct from mockups to HTML but in our experience, the results are variable and, in many cases the tools have fallen out of maintenance and/or are no longer available.
You could take a look at: https://www.yotako.io/ but I’m not sure either how good a job it does or whether it’s still supported.
On the issue of printing, we made a conscious decision to omit printing as, in our experience, most projects tend to be shared electronically and, for people who need to print, the single extra step of exporting to PDF then printing was not a deal-breaking burden.
There’s some great background reading on how we position ourselves at the link in my earlier reply.
I’d love to be able to give you a better answer but it’s likely that, if automatically exporting from wireframe to HTML is a requirement for you, we’re just not the right tool for that job.
