Thanks for this although I was responding to the OP who was having trouble setting up printing. Using the browser, as I understand it, you are only configuring cups as the administrator if you login as root. I wouldn't imagine that you could inadvertantly do anything really dangerous from the browser except possibly screw up cups. However, I do find it a pain to login as root just for this and so I will add this to my growing list of tasks to conquer ;) Regards Clive -- http://www.clivemenzies.co.uk strategies for business -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
