I don't think it's a printer issue.
I can see some use for these effects...display posters, marketing brochures, improved "lighting" effects...but there's no point without printability.
The 2nd issue with these is the right side window that pops up. It is a good idea but poorly implemented. The little thumb nail icons should be hard coded with high contrast images so you can see what effect they represent. They don't need to show the actual result. For minimal contrast effects, they're useless...too small to see anything. Once you've applied, game is effectively over.

Give me button to preview the shape with/without effect applied.
