the parallel connector supports three standard institute of electrical and electronics engineers (ieee) 1284 modes of operation: standard parallel port (spp), enhanced parallel port (epp), and extended capability port (ecp). if you configure the parallel port to operate in bidirectional mode, it supports the ecp and epp modes. when the parallel connector is configured as bidirectional, use an ieee 1284-compliant cable that does not exceed 3 meters (9.8 ft). use the configuration/setup utility program to configure the parallel connector as bidirectional.
complete the following steps to view or configure the parallel connector:
1. restart the computer.
2. press and hold the f1 key to launch the configuration/setup utility program.
3. on the configuration/setup utility menu, use the cursor keys on the keyboard to select devices → parallel port.
4. follow the instructions on the screen to save your changes and exit from the configuration/setup utility menu.
