The print range indicator that appears in the print configurator is an indicative print range.
As the print area increases, there may be deviations between the indicator and the physical print range to file.
What are the deviations between the indicator and the physical printout caused by?
- The map in the Map Panel displays by default in the Web Mercator coordinate system (EPSG:3857). The layout is used by most map services.
- For printouts, it is recommended to configure in the administration panels, the generation of printouts in a flat rectangular layout. Printing in EPSG:3857 is discouraged due to scale distortions on the printout.

- Accordingly, a transformation of the coordinate systems takes place. There may be slight deviations between the print range indicator and the actual print-to-file.
