Where are the settings in Win95 & XP to get the Printer Ports to go Bidirectional EPP or ECP Modes.

Um, what does EPP or ECP Modes stand for?

Its nothing to do with Windows per se, but is set in your BIOS.

Boot into setup (the key to press varies depending on the system) by pressing the appropriate key (usually displayed briefly at start-up) and often DEL, F1, or similar.

Find your parallel port and it hould be able to be set to Bi-Directional, EPP (Enhanced Parallel Port) or ECP (Extended Capability Port)

Save your settings and exit. Exact steps differ by BIOS type

EPP gives the bidirectional ability, which makes it much easier and quicker for scanners and external disks.

ECP is even "better" and adds DMA and various other goodies, which makes life easier for people writing drivers for clever printers. This will alos speed up the transfers for scanners, cameras, etc.

But some devices (including printers) can't handle ECP. Some must have EPP. Sometimes, to add to the fun, two units you have want different interfaces. :-(
