[luatex] Problem with drawing pdf

> This works fine on my screen. However, the circles are just missing when the document is printed. I guess it's just some minor(?) pdf syntax error that is ignored by the viewer but leads to problems with printers. Unfortunately, I don't have a printer here, so I cannot test things easily … does anyone have a hint what's wrong?

acrobat 8 tells me that your document is fine.
