Do you mean that the printing request has to be performed IN the
ada program or BY the ada program?
In the second alternative, you can assume that the (compiler/OS)
specific
ada runtime allows you to start another program. This procedure can be
encapsulted in a "to_port" package.
In the ada program: SYS_CALLS.CALL_SYSTEM(PRINTER_COMMAND & " " &
FILE_NAME);
PRINTER_COMMAND is shell script on UNIX, a command file on VMS, or a
batch file on DOS)
and submits the printing.
On unix the script is only "lpr $*"
