Bi-directional status reporting
|
|
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.
Note: For more information, refer to the IEEE P1284 document for parallel interfaces.
The bi-directional utility files are provided for support of operating systems and applications, such as Windows 95, that are capable of bi-directional status reporting with a printer connected to the parallel port.
You do not need a special cable; refer to Ordering Interface cables and adapters for information on ordering the standard parallel cable available from Xerox.
Note: Windows 3.0 and 3.1 do not support bi-directional status reporting.
Note: The printer is shipped with the uni-directional mode enabled.
- Follow the instructions in PC/Windows software to install the printer's software. Select Easy Install to automatically install the software, or select the Printer Utilities item in the Custom Install: Utilities window.
- Locate the files in the PHSR600 subdirectory, inside the PHSRTOOL directory created on your hard disk by the installer application.
- Select one of the following files.
- Use the BIDIR.PS file to enable bi-directional status reporting on a parallel port.
- Use the UNIDIR.PS file to disable bi-directional status reporting.
- Use one of the following methods to send the desired file to the printer:
- PC users: Use the DOS COPY command to send the file to the printer. (Windows 3.1 users can also use the Copy command in the File Manager.)
- Workstation users: Send the file to the printer as you would any PostScript file.
