It is a French program called "APrint", made by Patrice Freydière.
We are using it for it's various possibilities.  You can find it on

You will have to make your own instrument scale beforehand, because you
will find only French scales.

About our recent post on laser cutting for books and paper, it is clear
that the prices will become cheaper and that you may cut just one paper
or one book, but there is a lot of problem after just buying a laser
cutter.  It is not so easy even if you have made all the programs.

It has taken us more than one year to find solutions for the transport
of paper, and so on, and we learn more every day!  We are making also
all kinds of Ariston discs directly from a picture.
