How to select the right parallel port mode ?

In light of the popularity and variety of parallel port peripherals (Zip drives, scanners, and high-speed printers), you must take special care to configure the parallel port correctly in the PC's BIOS system setup program. Look for the parallel-port setting in the BIOS's Integrated Peripherals (or a similarly named) section. You'll probably find three options: SPP (Standard Parallel Port), the original (and slow) standard designed for old style printers; EPP (Enhanced Parallel Port) for parallel-port devices and printers connected to a device's pass-through connector; and ECP (Enhanced Capabilities Port, also known as the IEEE-1284 port), which may perform better with high-end laser printers. EPP is probably your best choice, since ECP doesn't always work with parallel-port devices that have a pass-through connector.

If you are having still problem, the next thing to do is to contact the peripheral's manufacturer or visit their web site for more information.
