Sources of information

We have employed three sources of information. We looked at printer output under a blue light and/or a computer microscope; we consulted press reports about printers (e.g. at Druckerchannel); we relied on printer manuals and other manufacturer statements. We welcome additional statements by manufacturers, resellers, or technicians.

Thanks to our friends at software firms and symphonies, public schools and physics labs, semiconductor fabs and ice cream parlors, in about a dozen countries around the world.
