I  have  not  looked  at  printing  because  there  are  terrible  hardware
dependencies.  There  is  no  way  to print anything but whatever flavor of
printer  language  *your* printer happens to use. It's just not portable at
all. If you do not care about portability at all and still want to write to
a printer, you would have to look at packet traces of clients accessing and
using  shared  printers.  Then  you could identify the proper semantics for
printing. It could be server/IPC$/pipe/...etc. I just don't know.

A  program should be written to model the concepts of the task it
performs rather than the physical world or a process because this
maximizes  the  potential  for it to be applied to tasks that are
conceptually  similar and, more important, to tasks that have not
yet been conceived.
