Thank you for replying McGiord.
Didn't realise you were online. This macbook has only ever been used by myself and has never been used for work, just web-based and mailing and music stuff. When I got it I was so over anything to do with Windows I immediately deleted or uninstalled all microsoft programs and I vaguely remember doing something with Bonjour, but it was all done in haste and, I confess, in ignorance. The printer and fax pane has always been completely blank and only now, 3 years later do I have the need to print. The need is so great I am prepared to reinstall the original software if necessary and that if means getting an external drive to back up music and photos etc then I will. I joined here though because I suspect there may be alternatives to such drastic action.
