- EPP (Enhanced Parallel Port) is a standard for parallel ports which

- peripheral devices.
-
- Some parallel port chipsets are slower than their motherboard, and
- so we have to control the state of the chipset's FIFO queue every

- Generally, saying Y is the safe option and slows things down a bit.
