Once you have entered SETUP, locate the configuration section for your PARALLEL PORT and modify it to read ECP. If ECP is not a choice, use a variation of ECP, such as ECP & EPP, or ECP DMA1. Save changes and reboot. Windows 2000 should recognize this and list the Item ECP Printer port in the Device Manager of the Control Panel/System applet under "Ports". If your PC does not support ECP, it will likely fall below the minimum system requirements for Windows 2000. It is also recommended that you install Microsoft Service Pack 1 for Windows 2000.
