I did the same. We had a tool that would let you export to pdf. That pdf would be sent to our customers. Initially we just used the print functionality in the users browser, but that caused output to vary based on the browser/os used. People complained that the PDFs generated were slightly different. So instead I had the client send over the entire html in a post request and open it up in a headless chrome with --print-to-pdf and then sent it back to the client.
