We have started a project for printing, however we are completely stuck when it comes to telling the printer what paper size is selected.
Everytime we select the paper size and hit print, the printer preview is showing A4 everytime and not our selected size although if we open the print preferences the correct size is selected.

I expect if we select A5, it tells the print driver to print A5,
If we select a custom "user defined" paper size, it tells the printer which size is selected. And not fixing this at A4 everytime
We cant seem to set the paper size outside the print dialog.
