A report can look perfect as a PDF and still print incorrectly. The reason is that PDF rendering and physical printing do not always use the same assumptions about paper size, margins, scaling, and printable area.
Check the whole printing path
- Confirm the page size inside the report.
- Check the printer driver paper configuration.
- Verify portrait versus landscape orientation.
- Look for scaling such as Fit to page or Shrink to printable area.
- Check whether the printer has non-printable margins.
Do not redesign too early
If the PDF is correct, first test printer settings and the driver before moving report objects. Otherwise a layout that was already correct may be changed only to compensate for a device configuration problem.
