Programming???

$ cat < /dev/ttyS0 &
$ stty raw < /dev/ttyS0
$ cat printer_file.txt >/dev/ttyS0
$ kill %1

I'm assuming your not reading anything meaningful FROM the printer but
that is a pretty fair assumption. Obviously you can add any other stty
commands to the same line or as separate lines.

You can practically do anything from the shell, you only really need
to program when things are quite time restrictive or the shell bogs
down with to much work.
