powerpoint vba to remove header footer, page numbers and date

[sxschech]

I found code to hide the page numbers and date from powerpoint 2013, which I assumed would have the same effect as clicki

on View, Handout Master and unticking Date and Page Number in the Placeholders section and then print the result to pdf with two slides per page without saving the pptx file. I tried two versions of the code, commented out and uncommented and the only part that works is saving the file to pdf. There are no error messages or code stoppage. Unfortunately, when I open the pdf, the headers and footers are still there for the date and page number. (I also originally tried the code within powerpoint's vba module rather than through automation and it didn't work there either)
