In this case, a marker which is visible in the images produced by both imaging modalities must be used.

Daisy wheel printing is an impact printing technology invented in 1970 by Andrew Gabor [1] at Diablo Data Systems.It uses interchangeable pre-formed type elements, each with typically 96 glyphs, to generate high-quality output comparable to premium typewriters such as the IBM Selectric, but two to three times faster.
