For Suite8, you’d need to do two things as a workaround to get the V7 PDF function working:
- The legacy.module_routing - see Compatibility mode in suitecrm 8?
- The PDF functionality as before in SuiteCRM 7 - see Print pdf in custom module and @rsp links.
It’s a bit of a workaround unfortunately, but it’s working smoothly.
There is most likely a (probably undocumented currently) way to use SuiteCRM 8 UI for that. Maybe you’ll find some hints here: Front-end :: SuiteCRM Documentation - if not, the “documentation” is the current code, so it’ll take some time to figure things out.
