Hello,
in the PDF24 Reader (part of the PDF24 Creator, since version 11.31.0):
- Open the PDF and click Print (or press Ctrl+P).
- Under Scaling select Actual size. The default is "Shrink to fit (never enlarge)", which makes pages smaller if they are larger than the printable area of the printer.
- Check that Paper size matches the page size of your PDF, and choose Portrait or Landscape under Orientation if needed. The preview shows the result before you print.
With "Actual size" the page is printed 1:1. Anything that lies in the non-printable margin of your printer is then missing on the paper. At the moment you have to select this option again for every print job.
If you are printing from another program, please let us know which one.
