Printers compatible with case sensitive hardened Mountain Lion For security improvment, I'm running all my MacOS X on case sensitive
and journaled file systems (then any ill written program which one day open a file named conf, and the day after try to open it with the new name CONF, won't mess with any of their or my files).

I'd like to buy a new multi-purpose printer
which would be compatible with such an hardened MacOS X.

If you are using a Mountain Lion on a case sensitive and journaled file-system,
could you share here which printer make and model you experienced running without any misbehaviour?
Epson Expression Premium XP-605 is installed and running correctly on
Lion (10.7.4) on top of a case sensitive filesystem.
The driver version I used is the 9.0.5 from the Epson web server.

This means that this software went through a quality control able to detect programming errors where the same file may be named differently
in different places of the source programs.
