print to printer

[hughLg]

I'm using Windows Me and Borland C++ Builder 5.5, I'm going to develop console application. How to write the function that print data to printer?

stdprn and some dos functions (e.g. bdos() and int86() is unavailable is not available in my builder...

You could try one of

FILE *fp = fopen( "LPT1:", "w" );
FILE *fp = fopen( "PRN:", "w" );
FILE *fp = fopen( "LPT1", "w" );
FILE *fp = fopen( "PRN", "w" );

It's been so long since I last did that, I can't remember what DOS device names look like.

If one doesn't work, check first to see if it created a file of that name containing your printed text, then try another name.
If you get no filename, and no output, then something else is amiss.

Remember to finish your output to the printer with

fprintf( fp, "\f" );  // page feed

This causes any data buffered by the printer to be committed to paper.
