We are using OOTB activity - HTMLToPDF to Generate PDF file. The Markup parameter is passed for this activity and that is getting derived through Property-Set-HTML.
We have observed that, the font size is decreasing when we pass pyPDFPageOrientation parameter as 'portrait' to this activity. When nothing is passed, (i.e. 'landscape' by default) the font size is appearing correctly.
