How do i change my output device when typing from screen to Printer? This is the scenario I have written a simple addition program in C and ask for the input when i execute a.out the input i give should be redirected to the printer as well as on the screen. Presently I am using # ./a.out > /dev/lp0
*snip* You use the shell's I/O redirection faclities outside your main program. This isn't exactly elegant.You must examine the dup2() call.
