I have installed slitaz-4.0 by the installer from an iso-file;
then I installed cups - all went well. The 'lpr -P printer file' worked ok.
But after rebooting the system the same printer command answered: 'Connection refused' and
the browser couldn't be connected to localhost:631 too.
After installing cups again all went well again!
This behaviour was reproducible.
Some ideas what went wrong ?
