IEEE 1284 transfer modes

configname: CONFIG_PARPORT_1284

Linux Kernel Configuration
└─>Device Drivers
└─>Parallel port support
└─>IEEE 1284 transfer modes
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
If you have a printer that supports status readback or device ID, or
want to use a device that uses enhanced parallel port transfer modes
such as EPP and ECP, say Y here to enable advanced IEEE 1284
transfer modes. Also say Y if you want device ID information to
appear in /proc/sys/dev/parport/*/autoprobe*. It is safe to say N.
