I had the same problems getting my lpt1 port to work with upgrading the firmware on my DesignJet 5000, and FINALLY figured it out.
First of all, build a straight up XP machine with a good parallel port. Windows 7 or 8 will give you nightmares.
In BIOS, make sure the LPT port mode is set to NORMAL. The first PC I used didn't have the NORMAL setting, so I found one that did. In theory the ECP or ECP+EPP setting should work as it is supported by the printer's parallel port, but I didn't have much luck. When properly configured, in XP under Device Manager, your LPT port should say Printer Port (LPT1), not ECP Printer Port (LPT1)
Second, DO NOT install the printer/driver in XP. If you do this, then the DOS copy command you use will send the file into the windows printer queue instead of directly to the LPT1 port. It will just sit there at 64K and do nothing.
Third, you don't need to reboot into DOS mode, in XP just go to RUN->CMD and open a command window.
type in the the copy command: copy /b DJ5000_Axxx.fmw LPT1 but don't press ENTER until you've pressed UPDATE FIRMWARE on the printer.
Lastly, I had to issue the copy command THREE times before it made it all the way to the end. It kept aborting with communication problems at around 90%-96%. The third time was the charm and it went all the way through.
