I have an Epson Stylus RX620 (Printer, Scanner, Copier). It's easy to print to but being hooked up wirelessly to the airport extreme is there a way to set it up so the scan feature works? Anyone do this? I need to scan some documents for a pdf file. Or will I have to hook it up directly to the computer. I'm running the 24" iMac C2D. Thanks in advance.
