Print multiple pages, but align to left hand side instead of align centre

I have a long document of 100+ pages which has been produced (not by me) by printing a PowerPoint document to pdf.

I would like to print this document with 3 pages to each A4, which I know how to do, but I would like to align these 3 pages to the left hand side to allow for annotations on the right hand side - they are currently being centred and I cannot see a way to change this.

I am using Adobe Acrobat Reader DC

Thanks
