HELP!  I'd hoped that V2 would solve this because V2 solved a similar problem I
had with piped output, but, it did not.  I am trying to write to the default
DOS printer (PRN, LPT1) and cannot.  The app's output goes to the DJGPP temp
directory and never prints.  Anyone have a solution?  Anyone try this?  I'll
post a code sample tomorrow.

In my Borland and other 16bit versions I just wrote to stdprn or opened a file
named "PRN" and voila!  Neither solution seems to work.  So ... HELP!

OK here is one version of the code (I've tried several):



#ifdef __DOS__
            output = stdprn;
            outstatus = TOPIPE;
#elif defined(unix)
            output = (FILE*)NULL;
            outstatus = TOPIPE;
#endif

...............

	    fprintf( output, line );    etc......


Another:

#ifdef __DOS__
	    output = NULL;
	    outname = "LPT1";
	    outstatus = TOFILE;

 ALSO TRIED: outname = "PRN"; outname = "LPT1:"; outname = "PRN:";

#elif defined(unix)
            output = (FILE*)NULL;
            outstatus = TOPIPE;
#endif

..............

	    if (outstatus == TOFILE && output = (FILE *)NULL)
		output = fopen( outname, "w" );

..............

	    fprintf( output, line );    etc......
