Paper size changes unexpectedly

[TonyRolfe]

Using LibreOffice Calc under Windows 11.

I want to force A4 paper to load from the rear tray of my printer (I’m printing on the clean side of used paper).

I changed the paper size to 209 wide rather than 210 and when I select File > Print the little preview looks OK and, if I print immediately, it works.

However, if I go into printer settings before printing and then return to the print page, the little preview shows a page size of 102 wide by 152 high.

Am I doing something wrong?

I changed the paper size to 209 wide

Where? In the Page Style dialog? In Properties of Printer Settings?

In the Format > Page Style dialogue.
