Printing in Ada

I have the Gnat 3.09 version for Windows 95 of Ada.  Is it possible to
send output directly to a printer instead of via a file.

Use IO redirection on the standard output (just like for C).

You could also try open'ing "lpt1:" if you have it attached. 
Of course the printer codes are not system independent, so your
code would not be portable.  

Alternatively, you can get the win32ada binding, and use Windows 95
calls to get at the printer.

I use gnat 3.09 under OS/2 Warp 4. Printing works by doing a CREATE
with "LPT1" (which is the name of the printer output channel) as file 
name and then writing into this file. The same should also work under
Windows 95; perhaps the printer name is different.
