Examples of using Z64 or ZB64 with ZPLII on Zebra

The Zebra ZPLII Programming Guide for x.14 talks at length about the
B64, Z64, and ZB64 input formats,
which are based on LZ77 compression and Base64 encoding. Darned if I
can find an example of an input
file in this format, or a tool that produces it. No joy trying either
ZTools or Zebra Designer, both of which
produce the older "advanced" ASCII hex format. Is the use of ZB64 just
a myth? What tool actually produces
the LZ77? gzip? pkzip? Something else written with zlib? Thanks! --
