Hello,
in the print dialog of the PDF24 Reader (version 11.31.0 and later; PDF24 Creator uses the same dialog), the Paper size is preselected to match the page size of the PDF. If your PDF has A3 pages, A3 is selected, even if your plotter is set to A1.
- Under Paper size select A1 (or Printer default to use the paper set in the plotter's settings).
- If the A3 pages should fill the A1 sheet, select Fit to page under Scaling. The default "Shrink to fit (never enlarge)" only makes pages smaller, never larger.
- Check the result in the preview and print.
At the moment the dialog does not remember the paper size, so you have to select it again for each print. We will add this to our list.
If you are printing from another program or the problem is a different one, please tell us which program and which PDF24 version you use.
