You may want to enlarge the instruction pages to see the detail in an intricate design more easily. Or you may want to change the size of the pricking pattern to fit a different card size.
The Foxit PDF reader has an option to scale the printout as a percentage. It is possible to enlarge the pricking pattern up to 130% on a single sheet. If you want to go even larger you can tile the enlarged page over multiple sheets of paper.
