   SUMMARY
   This article presents three methods an application can use to send output to a printer.
   MORE INFORMATION
   Method 1
   The first method uses the fprintf() function with the preopened "stdprn" stream. The following code example demonstrates this technique:
   #include <stdio.h>
   main()
   {
   fprintf(stdprn, "a line of text\n");
   }

   This method works only in the MS-DOS operating system because the "stdprn" stream is not defined by Microsoft Windows or Microsoft Windows NT.
   Method 2
   Another method uses the fopen() function to open the LPT1, LPT2, or PRN device as a file and uses the fprintf() function to write data to the file handle returned by fopen(). The following code example demonstrates this technique:

   #include <stdio.h>
   main()
   {
   FILE *stream;

   stream = fopen("PRN", "w");
   fprintf(stream, "a line of text\n");
   }

   This method works in Windows NT as well as the MS-DOS and Windows operating systems.
   Method 3
   Finally, in MS-DOS, an application can use the int86() or int86x() functions to call one of the following BIOS printer services provided by Interrupt 17h:
   service 0: send byte to the printer.
   service 1: initialize the printer.
   service 2: get printer status.
