Currently I'm drawing custom graphics using the OpenTK wrapper for OpenGL in drawing sheet views.  For example, I'm adding coloured lines and icons for certain features.

Problem is, this doesn't come out when printing.

Is there a certain way to accomplish printing of custom graphics in drawings?

I know there's a print notification callback that gives me the printer context.  I could potentially draw to that, but not sure I can use OpenTK for that.  So before going down that road, I was hoping someone knew of an easier way.

Thanks in advance.
