[Dev-C++] RE: Printing

[CARLSON, J. M. <CA...@st...>]

Reply to printing - take 2 - This is a good way to print from a console.  A
file could be created a console program and then printed with a system()
call.  Below is a sample program that demonstrates how it works.  It is
longer than it has to be to show several variations at the same time.

#include <iostream>
#include <stdlib.h>

using namespace std;

int main(void) {
  
  // assuming  c:\test.txt  exits,  this will work.
  // c:\test.txt should be a small file because it will print 4 times.
  // Notice the double backslash in the first non comment line
  // The backslash is a control characher so the first one 
  //     is stripped out before the command is executed.
  system("print c:\\test.txt");
  system("PRINT c:\\test.txt");
  system("print C:\\TEST.TXT");

  // Other ways to do the same thing.
  // This line could be dangerous - unterminated string
  const char* command01 = "Print C:\\test.txt";     /*  do I need \0 ?
*/
  const char* command02 = "Print C:\\test.txt\0";   /*  \0 ends the string
*/
    // This line could be dangerous - unterminated string
  const char  command03[] = "Print C:\\test.txt";   /*  do I need \0 ?
*/
  const char  command04[] = "Print C:\\test.txt\0"; /*  \0 ends the string
*/

  system(command01);	
  system(command02);
  system(command03);
  system(command04);


  // all valid dos commands can by used by system()
  // you can get a list of commands by typing 
  //     HELP + [enter key]  (if installed)
  //
  system("PAUSE");
  // notice case is not important to the system() call
  return 0;
  }
