Printing options

[faber]

I would like to have some more options when printing drawing: using the default line and converting the dxf file in pdf format, you will get very thin lines, difficult to read, especially when printing on small paper (A4).

Autocad (it is the eternal enemy...) is able to manage the printing without changing the existing drawing.
But I experienced a new problem; when asking to a friend to get more thick lines (using Autocad) he saved the drawing using a ... new layer's color!
Yellow means a thicker line (in autocad) while means I have to change the property of the layer when opening in qcad...
