OK thanks for clarifying.

Because I read "parallel printer port", I thought you were going to use 
ioperm (request permission), fcntl (open the port) and outb
(send a byte to the port) to print a file.

That's why I thought using "lp" or "lpr" would be easier.

But anyway as I also wrote it is possible to look at the GNU smalltalk
C interface possibilities which may be interesting to you ...
