I use Layout to make shop prints for welders and fabricators. A fence post with multiple style of fittings we have modeled with tags to be able to turn on and off different items like a latch catch. When I look at this on my screen everything looks normal. When I print the page there are other parts that show up on the printed page and they have no color. When I update the model link it fixes itself.
It would help to see the LO file so we can see how you’ve got it set up. Are you printing directly from LO or are you exporting to PDF?
I am printing straight from Layout. I have not had this type of problem with the PDF yet.
