Es tu bien à la racine de ton cdrom d'installation lorsque tu tapes la commande, es tu en root ?
Ci-joint un extrait du readme pour ceux qui participe :
INSTALLATION
------------
You need to be logged in as the super-user (root) to be able to install this
package.
- Run the 'setup.sh' script on the CDROM to launch the installation program,
if the installer didn't start automatically upon insertion of the CDROM in
your drive.
- You may choose either the "Recommended" or "Expert" types of installation.
"Recommended" is fully automated and won't require any interaction on your
part. It will install the product under /usr/local/linuxprinter.
The "Expert" installation allows you to fine-tune these settings and choose
where the package will be installed.
- Once the installation is done, you will be offered the option to start the
Configuration Tool, which allows to install and configure new Linux printers
into your Linux system.
- The configuration tool can later be launched by using the 'linux-config'
command, or through the menu item that may have been added to your Gnome / KDE
menus.
(en tout cas merci pour l'info si je dois me racheter une laser je crois que je ferais le même choix que toi).
