To elaborate a little, "IPP Everywhere" / AirPrint, "Driverless printing" or whatever it's called, is basically having the printer run a CUPS server and broadcast itself on mdns/bonjour, and then clients can print to it directly without having to install manufacturer-specific printer drivers (the IPP protocol itself has the necessary features so that you don't even need PPD's). The only thing the client needs to be able to do is support IPP and a few file formats mandated by IPP (PWG-raster (a simple raster format) and JPEG, even PDF is optional IIRC). (There's something called the "IPP sharing extensions" (IIRC) for supporting things like central print servers with auth, proxying and whatnot for enterprise deployments)
