Dot matrix printers

[Delprete, Piero]

 These two messages about pens with permanent ink reminded me of the
specimens labels made with dot matrix printers. I noticed that some herbaria
are still using this kind of printers, and I can assure you that those
labels will fade away within a few decades. Some of them are already
difficult to read.

A word of caution with India Ink and related inks.  DO NOT freeze.
If these inks are frozen, then they will not be permanent.  Water and/or
alcohol will make the labelling "run".
