Error code 79 after the 2605fw_20120413.rfu firmware "update"
As of this writing, I could not find the 20071108 firmware on the HP sites. I found it here:
For Mac OSX 10.8 users, I opened the dmg and went to the 2605_FW_Update-20071108.app/Contents/Resources directory and used the following command:
lpr -l jedi.11.15.allcodeflashsys.rfu
The printer is back to normal now.
