Some system utility tools allow printing system details to a PDF file (as well as plain .txt).
The fontsize is pretty large, like Arial 12.
Is there a way to control this?
Like setting it to Arial 10 or so.
I tried with exporting the created PDF to Word .docx but then the font changes (arial to times) and bold font changes to non-bold, etc.
If you are referring to change font size before printing PDF, you can do it using Adobe Acrobat DC application.
Could you please let us know the dot version adobe application and OS you are using.
If you have a different issue let us know.
When you print to PDF there are no font or size options. The font, size, line breaks, every detail is decided by the tool which prints. Check whether the tool offers such an option, Acrobat does not.
