Parallel Port connection possible?

[AEN007]

3May2008

Greetings.
So I have found that TCUP supports
the parallel port connection, but
could/would anyone explain to me
why the Total Commander Ultima Prime 3.7
listing at Download.com says -
"License: Free
Limitations: No Limitations"
while the startup splash screen says -
"This is shareware. You can use
this fully functionin demo free for 30 days
after which you must register or remove the software"?

Please reply/advise.
Thank you.
Regards,
