Thread: Printer

I'm not exactly a C wizard, and I can't program using ports. I'd write all the data to a file and use:-

Code:

system("copy file.ext prn");

or

Code:

system("type file.ext >prn");

Basically this is getting DOS to do the work for you. And if you aren't using pure DOS (Running COMMAND.COM under Windoze) I'm not sure Windoze will like it.

i don't know if those particular commands are valid, but printing to the printer using dos stuffs under windoze 98 works for me.

I once heard that you need to write to drivers, otherwise, im not the best person to ask.

There are a bunch of ways in DOS, here are two

Code:

#include <stdio.h>
main()
{
	fprintf( stdprn, "Something to print\n" );
}

#include <stdio.h>
main()
{
	FILE *stream;
	
	stream = fopen( "PRN", "w" );
	fprintf( stream, "Something to print\n" );
}

LPT1 and PRN are pretty much identical - LPT1 is the id for Parallell port 1 and PRN is the default parallell port (almost always LPT1) - Anyway, I don't think you can address LPT1 from C with fprintf, etc.
