I've got the HP Photosmart C7283 and it allows Bluetooth connections, provided you have a dongle, but it only allows photo prints(=photo paper). Just my what I've experience with the bluetooth functionality.
wifi? you can get wifi devices that let you plug up to 4 printers into them, and share them over wifi. works with scanners too (some). Works with samsung, and HP and lexmark but my epson photo printer doesnt like it.
