Since I've upgraded the operating system to 10.6.4, I lost the connection to the printer. Printer was working fine with Airport Router, thru USB connection in previous versions. I deleted the driver on the MacBook, and now I don't even remember how to reinstall the driver, to at least bypass the router.. Immediate need is to print, as quickly as possible, then I need to setup thru the Airport. My daughter starts summers school, and will need access to printer. Any ideas, help, please let me know. Thank you. Frank
