	OK. The problem seems related to /dev/parport0. Check its rights:

#ls -l /dev/parport0
crw-rw-rw-    1 root     root      99,   0 mai 20  2002 /dev/parport0

	it should be rw for any users. Also check that ppdev character device is
loaded:

#dmesg|grep ppdev
ppdev: user-space parallel port driver
