Any idea using the wkhtmltopdf to produce/print our Report Card if possible to add watermark logo that will show at the center of the page when we print the report card?

With custom CSS (in a custom theme, in the stylesheet_wkhtmltopdf.css file) this could be done.
stylesheet_wkhtmltopdf.css
The PDF content has the .wkhtmltopdf-body-wrapper class and #pdf ID. https://gitlab.com/francoisjacquet/rosariosis/-/blob/mobile/functions/PDF.php?ref_type=heads#L147 The Report Cards PDF content has the .modname-report-cards so you can scope it.
.wkhtmltopdf-body-wrapper
#pdf
.modname-report-cards
Or you can try adding your CSS to body which has no CSS class... I have not tested it.
body
