Very Very solid advice if I do say so myself. This is a bit over my head but I will try to figure it out. Thanks for all your help.

Rather, limit the permissions to that group.

Each permission set is controlled by a bit string that is 4 bits long. If the first bit is a 1, then that group has read permissions. A bit string (base 2) of 0001 has a decimal value of 1 because 0x2^3 + 0x2^2 + 0x2^1 + 1x2^0 = 1 and corresponds to execute permission A bit string (base 2) of 0010 has a decimal value of 2 because 0x2^3 + 0x2^2 + 1x2^1 + 0x2^0 = 2 and corresponds to write permission A bit string (base 2) of 0100 has a decimal value of 4 because 0x2^3 + 1x2^2 + 0x2^1 + 0x2^0 = 4 and corresponds to read permission The fourth bit is used for special permissions like "the sticky bit" and is really beyond the basics. Now, because the values of 1, 2 and 4 are bit-independent, any combination of those values is the equivilant of 'OR'ing the bit strings. So, if we want read and write permission we want both 4 and 2. That is we want the bit mask to be 011. Which is 0x2^3 + 1x2^2 + 1x2^1 + 0x2^0 = 6. Which is what you get if you add 4 + 2. So a mask of, say 751 is RWX for Owner, R+X for Group and R for World. As for which link to follow --- without your box in front of me to troubleshoot, I really can't say "here's what to do." However, I'd start with setting your library to minimal permission since what you're getting is a permissions error. That would be at least as strict as 660. I would also then check that your users are in the same group as your print service -- which is usually 'wheel,' but not always.

'chown root:root brfaxfilter' I will then 'chmod go+x' ???? Can you please recommend which area of the link you sent I should possibly follow? There are chmod 555 and 700 's etc making me confused. I will restart 'cups' using the command 'sudo service cups restart' Thanks alot for your help with this.

Anyone authorized to use the service should be in the same group as the service.

It really only probably needs to be 'rw-' for owner and group, and then any user who is allowed to use it should be in that group. There should be no need for a sticky bit to be set.
