I would like to know if usb bluetooth printer adapters, such as the "Belkin Bluetooth USB Printer Adapter" and the "EPoX Bluetooth Printer Adapter", will connect a CanoScan LIDE 20 scanner to an iMac G5 17'' 1.8Ghz. If not, can you please inform me what will.The imac does not have built-in bluetooth, but if I can connect the scanner, I will purchase an adapter.
