This was copied a minute or two after running the command mentioned above.
The sections that say "avrdude: Send:" and "avrdude: Recv:" over and over continue on for a while with intermittent "out of sync" or "failure to execute command" errors spliced in.
Eventually the program just stops and the firmware still hadn't taken.

It seems that AVRDUDE is starting to upload a file, but for some reason it times out before it can finish or something.
There is a green LED that flashes underneath the printer every time a new section of send and recv appears.
When I try other '-c' parameters (like arduino) I just get an "out of sync" error after about three sends that each have one recv.

I couldn't copy any more command prompt stuff since the whole "memory blocks" dump is longer than the command window.
Anything else was repetition mostly of what is seen above, anyways.

" avrdude -C[path]/avrdude.conf -v -v -v -v -patmega1280 -cstk500 -Pcom3 -b57600 -D -Uflash:w:[firmware .hex file]:i "

I see you found a solution, but if this is the exact command string you've been trying, I think that may be your problem. Now I don't use AVRdude or even flash my printer, I just use the arduino IDE when programming my chips, so I may be way off here. But the bolded section usually needs replaced with a legitimate file name, not a generic place holder.

Edit: Dangit, didn't see the OP date.
