Can I get some help please? I have just bought an iMac and I have hard wire connected it to my router, My windows vista PC is also connected to the router. Both machines have internet access via the router and that works fine. I have a brother mfc-290c connected to the iMac via USB but I can't print to it from the PC. the iMac doesn't show the PC or network in Finder. The PC can see the iMac but I cant connect - it asks for a user name and password. I have turned on every printer sharing and file sharing thing I can find but it won't work. Am I just a PC convert who can't drive a Mac yet and there's a blatantly obvious solution?!! Thanks. Dave
