After a good hour on the phone trying to get my newer iMac to work with my epson workforce (short story: printer printed/scanned fine through network from both macs until one day when it just didn't, got it to print/scan with older imac not newer one), the tech finally gave up and said its obviously an OS problem. HUH? What could I have possibly done to one computer that made this OS all of a sudden not like my epson? and if you're psychic: WHY DO I ALWAYS HAVE PROBLEMS WITH PRINTERS!!! THEY ALL SUCK!!!!! THEY ALL STOP WORKING OR HAVE PRINTING PROBLEMS AND NEVER LAST MORE THAN A FEW YEARS!!!! That felt a little better....but seriously, WTF with the OS excuse?
