No reason why we can't both be correct -- just concerning different
packagings of the software. Thus:
My comments were based on retrieving and unpacking
pips-sc64_63s-2.6.2.tar.gz, the source tarball for Epson's Stylus C64
drivers (i.e., the printer being asked about). Admittedly, I didn't
look through that tarball's contents very thoroughly: I pretty much
stopped digging upon finding this sort of stuff in the "Epson Kowa
Public Licence" (file COPYING.KOWA):

But since you ask, the tarball contains a "lib" directory with the

It seems a fair bet that that's where the "secret sauce" in this case is

Obviously, I have no idea what you have on hand; for all I know, it's
rather likely that Epson are pulling this trick for some models and not
for others (given their generally good reputation for cooperation).
However, if you want to apply the acid test, try recompiling for, say,

Ja, my impression is that inkjet manufacturers typically get that
funny-but-not-amusing attitude only concerning a few models at any given
time. Presumably, those tend to be some of the ones subject to the
highest levels of price competition, that include some fancy
software-level tricks that are considered trade secrets.
