Firefox (like all prebuilt binaries) can be sensitive to GTK issues.

There are known issues with Mozilla and GTK that present this SAME
way:  https://bugzilla.mozilla.org/show_bug.cgi?id=430818
<https://bugzilla.mozilla.org/show_bug.cgi?id=430818>
If you read that post they discuss reinstalling another version of GTK.

A command line print to lpr is a completely different program etc.
If you didn't do the two options above, adding your default printer name,
how can you expect it to be inherited in firefox as the variable name
MOZ_PRINTER_NAME? Also add to your ~.bashrc file:

export MOZ_PRINTER_NAME=printer-name

There are a few links that indicate an UPGRADE will break printers.  Is
this a Firefox upgrade?

Correct, Mark, if you upgraded Mozilla or never used this Firefox printer
yet, you are not going to see it (that's what that red means up there...)

I tried adding a print.print_printer entry, and then reset it, but it is
just an empty string. There are no instructions on how to manually add the
printer.....the red text was not very helpful. (I don't mean you are not
helpful, just I ran across this info earlier in one of my many google
searches on this problem, and found the red text somewhat humorous and not
very helpful).

Try setting your print.print_printer to Officejet_Pro_L7600

Be sure you have added the ~/.bashrc entries above.

Please give us an idea what linker libs Firefox needs using:

# ldd $PATH/$FIREFOX.bin

I guess I expect it to find all the printers, and not make me add them
manually, like every other program. I would add it manually, if I knew how!
I have tried various combinations of Officejet_Pro_L7600 (see the lpoptions
output above), and then resetting firefox, but it never shows up in the
printing dialog. I have also tried the option of using gtklp instead of lpr
in the print.print_command option, but no luck there either.

Gee, if you reset all those options and restart Firefox, (after adding the
"default lpr" and .bashrc entries) and you still don't see a printer,
please reply with the ldd info, so we can verify which GTK libs and linkers
it's needing?
