Thanks to Mike @Licensecart I was finally able to reduce the File Size of my PDF Invoices.
And wanted to post it here for anyone else that could use it.

Worked perfectly when I changed the font from a " custom " one I installed to helvetica.
Instead of my invoices being a whopping 1.4 MB
They are now only 453 KB !!

Thanks again, Mike.
