Phaser 540 Color Printer
Parallel port
The printer has an asynchronous parallel port that lets you interface with
PCs. The parallel port supports uni-directional and bi-directional
communications (refer to the Phaser 540 Drivers and Utilities Printing
Reference for instructions on setting the port to bi-directional
communications). For bi-directional communications, the parallel port
supports two modes: Compatibility Mode and Nibble Mode.

communications (refer to the Phaser 540 Drivers and Utilities Printing
Reference for instructions on setting the port to bi-directional
communications). For bi-directional communications, the parallel port
supports two modes: Compatibility Mode and Nibble Mode.
The interpretation of interface signals depends on the current mode.
Compatibility Mode provides host-to-printer communication in a manner
compatible with a uni-directional interface. Nibble Mode provides
printer-to-host communication and may be combined with Compatibility
Mode to provide bi-directional communication.
