I couldn't understand the license very well, but I don't think we can
redistribute the binary.  It would be good we ask the vendor
explicitly and confirm it is OK for them.  In the licence, it only
allows the distribution to "third parties" or "a third party", which
is quite ambiguous.  If I understand the word correctly, "third party"
is not users nor venders.

Besides, just my feeling, isn't it a "free-ride" of Ghostscript system
or Debian GNU/Linux system?  I don't see any reason to support such
software or printers.

Further, the lincense seems to be a kind of contradiction:

How we can modify the code without source code, and being prohibited
to decompile/disassemble or reverse endineer?
