Unable to print "/dev/lp0": Permission denied

[Francois Massonneau]

Hello,

Today I tried to print something on my Brother printer which used to work 
fine when I was running FC3, but today, narda, nothing. It doesn't want to 
print anything.
I tried to print a test page as root, but again, it doesn't want.
This is what I find in the /var/log/cups/error_log file :

As reported in the log file, I get a :
E [22/May/2006:14:53:36 +0200] [Job 21] Unable to open parallel port device 
file "/dev/lp0": Permission denied

But even as root ??
Thank you in advance. Francois
