Frans,
How to print:
In "Edit->Current drawing preferences" select "units" and set "Main Unit" to "Meter"
In LibreCAD coomand line write:
command:  line
Specify first point:  0,0
Specify next point: 2000,0
Specify next point or [undo]: 2000,2800
Specify next point or [close/undo]: 0,2800
Specify next point or [close/undo]: close

This commands draw a rectangle of 2000x2800 units (by convention meters) ergo 5600000m2 or 560Ha

to print on A4 (210*297mm) the best scale is 1/10000:
2000m/10000*1000mm = 200mm width
2800m/10000*1000mm = 280mm height

Select "File->Print preview"

to the right of the "Pen Selection" toolbar appears a new toolbar
In the new combobox select 1:10000 or write 1:10000 or write 1/10000
press the second button (center on page), then select "View->Auto Zoom"
It should be a rectangle centered on the A4 sheet occupying almost the entire sheet
and ready for print.
