How to print construction layer?

How to print construction layer? I switch print icon construction layer on print, but it is not printing.

It is the purpose of a construction layer to provide auxiliary lines helpful to make the drawing but which are not thought to be a visible part of the drawing. So probably LibreCad has been designed not to print construction layers at all.

Perfectly explained dellus.

In fact this is how it is designed, the construction layer property disables layers in print preview and printing.

Thus you have to disable construction property to print a layer. If you want construction lines extend beyond the paper size, you have to extend them manually when construction property is off.
