De rien

J'utilise le logiciel fourni par graphtec, un plugin illustrator du nom de cutting master. Je ne sais pas s'il est compatible avec votre plotter en revanche...

En gratuit :
il existe inkcut mais je crois qu'il ne fonctionne que sur linux : http://sourceforge.net/projects/inkcut/?source=navbar

En payant il y a :
Flexi : http://www.thinksai.com/French/ (j'utilisais celui là au début)
Omega : http://www.gspinc.com/OMEGA
Casmate : http://www.fcsrl.com/en/Cutting-Plotter-and-Software/casmate-basic.html
Signlab : https://www.cadlink.com/index.php/en/signlab-version-9-1
Vinyl master cut : http://www.vinylmastercut.com/buy/

i'ts a little vague to give you a precise suggestion, but for an electronic brand you should stick to a sans serif. http://www.dafont.com/theme.php?cat=501

essaye de la désinstaller et passe par un soft de gestion de polices : http://www.dafont.com/fr/soft.php#1

(almost) every font have numeric glyphs...

Try to use a font management program. It's easier to manage your font library that way.

If you don't respect graphic design from other people, then you're a terrible graphic designer. Try to Google the word "ethic"...
it's easy to organize your font collection. You can create separate folders for each license type while you download a font or, even better, organize it in your font management program.
See, easy.
