Make sure the printer’s parallel port is available. In some configurations,you may have to re-install the Centronics® I/O cable and connector inorder to load basic software into the printer.2. Make a configuration printout of all saved configurations. (Refer to theUser’s Manual.)3. Set the printer power switch to O (Off).4. Disconnect the data (signal) cable(s) from the printer interfaceconnectors.5. Connect a parallel data printer cable to the LPT1 port of an IBM-compatible computer running the PC-DOS, MS-DOS, or Windows (3.1x,95, 98, Me, NT, 2000, or XP) operating system.6.

Open the readme.txt file on the CD-ROM. There are emulation sets withcorresponding part number files from which to choose. All emulationsinclude the program file or emulation code. They are offered in two fileformats: .exe and .prg. Use .exe files to download through the parallelport.12. Identify which emulation set you want to load into the printer and note thefilename that corresponds to that emulation. The filename is a six digitnumber plus .exe. For example: 123456.exeThis is the file you will download into the printer.13. Copy the file to the download directory you created in step 8.14. Start a command prompt session.
