Chapter 4
Downloading Software through the Parallel Port
10. Open the readme.txt file on the CD. There are two emulation sets with
corresponding part number files from which to choose:
CT / IPDS / PGL/VGL / ZGL / TGL / IGL / STGL / DGL / MGL / IEGL
TN / PGL/VGL / ZGL / TGL / IGL / STGL / DGL / MGL / IEGL
Both emulation sets include the LP+ emulation. They are offered in two
file formats: .exe and .prg. Use .exe files to download through the
parallel port.
11. Identify which emulation set you want to download into the printer and
note the filename that corresponds to that emulation. The filename is a six
digit number plus .exe. For example: 123456.exe
This is the file you will download into the printer.
12. Copy the file to the download directory you created in step 8.
13. Start a command prompt session. (The Start Menu icon is usually labeled
MS-DOS
14. At the command prompt type:
C:<Enter>
cd \download<Enter>
15. Enter the following command:
filename.exe -pb<Enter>
where filename.exe is the file name you noted in step 11. This command
takes the file on the hard drive and copies it as a binary file into the flash
memory on the printer controller board.
IMPORTANT
Do not interrupt the downloading process once it has started.
Interrupting a download will leave the flash memory on the controller
PCBA incompletely loaded, and the printer may not boot up.
While the file is copied into memory, the printer LCD informs you of the
download process and status.
16. When the new software has successfully downloaded into flash memory
and the printer has reset itself, set the printer power switch to O (Off).
17. Remove the CD from the host computer and store it with the printer.
18. If required, reconnect the data input cable(s) to the printer.
19. Set the printer power switch to | (On).
20. Using the configuration printout(s) you made in step 1 on page 267,
restore the printer configurations.
