NAME
       kdk_printer_get_status -
       <?><?><?><?><?><?><?><?><?>(<?><?><?><?><?><?><?><?>)

SYNOPSIS
       #include <libkyprinter.h>

       extern int kdk_printer_get_status(const char *printername);

       Link with -lkyprinter.

Detailed Description
       The main function of the interface is to obtain the current printer
       status (status is not updated in real time).

       The argument printername is printer name, kdk_printer_get_list returned
       value.

RETURN VALUE
       On success, returns status code of type int.

       On error, return -2.
