## Notes

- The default `perSheet: 2` places two pages side by side on each sheet, which is the standard booklet layout for duplex printing.
- Blank pages are added automatically if the total page count is not a multiple of the sheet size.
- Print the output double-sided on short-edge binding, then fold and staple.
