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 ...
