Background.
Lightroom provides very powerful tools to manage images and their related metadata. Unfortunately, the ability to place professionally formatted metadata or text on the same page as a print is sadly lacking. However, the functionality required is substantially already working within the Lightroom Classic App, but only in the Slide Show Module.
Details.
Please add the existing Text Overlay features within the Slide Show Module to the Print Module. The functionality can be added substantially unchanged, with perhaps some relevant tweaking to respect the characteristics of a Printed Page rather than a Slide. I can think of 2 specific tweaks required.
1. Align the text with the edge of the Image rather than the edge of the screen.
2. Provide the option in the Text Overlay panel to specify a font size.
I enclose a worked example within the attached pdf / jpg.

I have requested this feature way back as far as Version 1. I suspect I am using a different UserId now and cannot find my original requests.
I come across this requirement regulary and I show people how to achieve this via other non Adobe tools, as it represents a real world requirement for those who wish to print Fine Art / Portfolio style prints. I have given up trying to use Photoshop or InDesign, as the tools available in these apps are non intuitive, out of date and seriously too technically challenging and ergomomically a disaster to coach / teach photographers how to use.
Such a pity that Lightroom provides such powerful tools to manage metadata, but fails to make it feasible to use this metadata in prints in a professional manner, with control over what metadata field to include, where to place it and what fonts to use.
