Thread: How to print?

FILE *fp
fp = fopen("LPT1","w");
this opens the FILE stream to the printer in port lpt1

-Luke

Example:

Code:

#include <stdio.h>
#include <stdlib.h>

int main()
{
 FILE *printer;
 printer = fopen("LPT1","w");
 fprintf(printer,"TEXT HERE");
 return 0;
}

make sure to have the \f escape sequence or else the printer will not no when to stop accepting input and print

perhaps it should be moved to the FAQ (Hint hint, mods)

Another approach:

Code:

#include <stdio.h>
#include <stdlib.h>

#include <stdio.h>
#include <stdlib.h>

int main(void)
{
	 FILE *printer = fopen("LPT1","w");
	 FILE *fp;
	 char str[256];
	 char buf[BUFSIZ];
	 printf("File name? ");
	 scanf("%s",str);
	 fp = fopen(str,"r");
	 if(!fp)
	 {
	 	printf("File does not exist\n");
  		return -1;
 	 }
 	 fgets(buf,sizeof buf,fp);
 	 while( fgets(buf,BUFSIZ,fp) != NULL ) 
	 {
  	       	fprintf(printer,"%s",buf);
	 }

 	 fprintf(printer,"\f");
 	 return 0;
}

shadow, i found that also, and from you!

thats why I posted the second code with *printer instead, I forgot it needed to be that
