Currently I can find a python interface to plot individual PCB layers to PDF with one PDF per layer. If I try to plot multiple layers to a single PDF this does not work. Now this is expected as even the plot GUI does not have a method to plot multiple layers to a single PDF.
My question is then, how can the Print interface be used to generate a single PDF with multiple layers? Looking at the print dialog window this can be done but I can’t seem to find this ability within the python API. Is the ability there?
