Consider the sentence:
Die Aufgabe des Technikers ist es, die Fahrkartenautomaten mit Geld, geeignetem Papier und Druckerfarbe zu versorgen.
My spellchecker did not know Druckerfarbe and offered Druckfarbe as a substitute.
Duden says that Druckerfarbe is a synonym for Druckfarbe. However, I think that the first can potentially refer to the color of the machine itself, while the second relates to the color of the printed stuff or to the color used for printing in any case. After all, to draw an analogy, Himmel(s)farbe is the color of the sky, and Druckergehäuse is the casing of a printer, so, by analogy, Druckerfarbe should at least allow for the meaning "color of the printer".
Now, I think that the right term would be Drucktinte or Druckertoner anyway, since the color is an abstract concept, while the ink/toner are chemical substances which can run out and which one can replenish or not replenish. What do you think would be the right term in the above sentence?
