Is NVRAM information on a given device only accessible through a GUI/ command line NVRAM dump on a particular device or is NVRAM information more like a harddrive that could be mounted on another device?

No way to answer your question as posted. We will need actual details on what you mean, what device(s) you want to probe, version/distro of Linux, etc., before we can even *TRY* to guess.
What is your goal? Can you clearly explain what you're trying to do?
Wish to understand so as to know whether a password on say an old WRT54GL or even active HP, Epson, Brother, or whatever printer could be recovered if one wished to. Then can weigh risk in using non-unique password on these devices that use on other more important things.

There is a huge difference between it **COULD** be done, and how easily it can be done. If you'd want to spend the time prying chips off boards, shoving them into EPROM readers, getting that going, decoding the information, etc., then yes...it COULD be done.
Are you going to spend many hours doing it, or are you just going to do a factory-reset in 10 seconds, and set your own password?
