Presetting print options in PDF

We have a requirement where generated PDF documents  sent to customers over email and we need them to open the PDF and directly trigger print without main making changes in printer settings.

Will presetting print options in PDF will always override the default printer settings especially Page size, No Scaling & PPI?

Note: My end customers having different versions of Acrobat PDF Readers and the different printers to print these generated documents.
