Clipping Planes and sections not printing line thickness

Hi

I am having trouble printing sections and clipping planes at the desired thickness.
I see other people have asked the same question but there has been no responses.

I have attached a piece of the model for reference.
The clipping plane and sections show up on the layout as the desired thickness but when i print it physically, the lines are all the same. The print thickness and display thickness are the same.

I have attached the printed pdf page too for reference.

What am i doing wrong here?

Many thanks

@Japhy can you please look into this

Hi Marc,

Is the intent to be printing from the Pen Display Mode?

Hi Japhy

I have tried printing from all different displays. They are all the same.
