Thank you very much for the quick replies. The idea was to use the printer installed on the XP Desktop PC to print all doc's from Laptop Vista without connecting Laptop to router by cable, you see this would be a problem my Vista Laptop in use three floors higher than XP Desktop PC creates a problem with cables.
Thanks also to ACtheTROL 'your' solution filled the bill perfectly, all is now in full running order. Again many thanks it is nice to have the brains, mine are a little dull with old age, but with a little help now and then I get there.
