According to our computer specialist who works with samples from fresh-
water investigations, the paper quality is essential. Ordinary type-writer
paper won't work, the surface will dissolve in alcohol and the characters
are lost. For labels we have as long as I can remember (35 years) and
probably long before that, used the best paper quality legally available
(money quality is not!).
Photocopying will not work, the symbols will eventually be washed off. To
day we use a laser printer, but I really do not know what those labels will
look like in a hundred years.
