Writing 0x80 to the port 0x402 above the parallel port data register (typically 0x378) sets the port to EPP mode. After similar problems, we added this to the driver for our boards. This problem is NOT unique to the D510MO, a fair number of Dell computers have the same problem. I have a program "pcisetup" in various forms at http://pico-systems.com/codes/ for newer ubuntu OS'es you may need to recompile from c source. Run the program with root privileges.
