 Caution: The 25 pin Parallel and 25 pin Serial interfaces look exactly the same externally.  They both use a 25 pin D-shell connection.

A closer look will reveal that the electronics on the actual interfaces boards are different. The best way to determine which 25 pin communication interface is present in the printer is to print a configuration listing from the printer. This listing will show either RS232 Serial or P1284 Parallel. See Manual Configuration for how to print out this listing.
