I'm trying to send RESET to USB printer (Samsung SPP-2040) using the
following code:

#include <sys/ioctl.h>
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <linux/lp.h>
#include <linux/usb.h>

int print_d, ioctl_return;
 unsigned int   status;

// printf ("LPRESET=%d\n",LPRESET);

if ((print_d  = open("/dev/usb/lp0",O_RDWR|O_EXCL)) == -1 )
        {perror("open  lp0 failed "); exit(1);}

if ((ioctl_return  = ioctl(print_d, LPRESET)) == -1)
        perror("ioctl failed ");
}

but I'm receiving  "ioctl failed : Inappropriate ioctl for device"
message.

What's wrong with this code?
Thanks,
Vitaly
