Printing?

Sorry if this is a stupid question, but I was wondering.
Is it possible to print something from a program. For example, say I would like to display "Lala" on the screen and then print it out. Is it possible? If so, are there any resources to help me learn how to?

Yes.

Unfortunately there is no support for that in c++. You will have to use some other libraries/tool than thoose in standard c++. If you are programming in Windows there are surely some useful resources.

The search feature of this site is fairly useful.

I don't have all my references with me, but if you are running DOS (I mean true-DOS not a DOS-window) or Linux, it should be easy.

This is C , but you can try it...

Code:

#include <cstdio>
int x = 5;

fprintf(stdprn, "The answer is  %d ", x);

There are a couple of issues with Windows that I know of. I was never able to get my Windows console programs to print using standard C++. I think there is a way to do this, if your printer supports "DOS".

You might have to use the Windows print functions, in the <windows> header, that work via the Windows driver supplied by the printer manufacturer. Some printers (like my Canon) won't print if you just send ASCII characters. The printer simply won't work without the using Windows drivers / functions.

Might be an issue with capturing a printer port, I don't think Windows does that as a default for any printers you set up. You have to go to your printer settings, right-click and look through all the options there. One of them should say something like "Capture Printer Port". You just need to make sure LPT1 is captured for your printer. Just a thought...
