"jobId": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
"downloadUrl": "/api/v1/download/a1b2c3d4-e5f6-7890-abcd-ef1234567890/document.pdf",
"originalSize": 2450000,

}

## 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.
