Printing should not be a final problem
Teachers often prepare a worksheet quickly, but lose time at the final step because the printed version shifts, breaks across pages, or looks different from the preview. A stable PDF export solves that issue by preserving the layout exactly when the document moves from browser to printer.
Schools need a portable format
PDF remains useful because it is simple to share between devices, print in school offices, and keep in digital archives. Teachers can send the file to another colleague, print it later, or store it for reuse next term without worrying about layout changes.
Consistency builds trust
When the preview matches the PDF, the teacher trusts the tool more. That trust matters. It means the teacher can review the worksheet once, export it, and move on to the next task. In a real school workflow, that reliability is more valuable than extra visual effects.
