Today wi-fi printers usually use some proprietary protocol (and with my Canon and HP printers I had nothing but trouble). Currently the only way to print over the net without drivers is to use Postscript-capable, or possibly PCL-capable, printers with support for LPD or IPP protocols. That's common for network laser printers, but not for cheap consumer inkjets. So if Apple can get manufacturers to support a common protocol for network-enabled consumer-level printers, that would quite an improvement. At least for Apple users...
