    #include <stdio.h>

    int main()
    {
        int index = 0;
        //获取打印机列表
        char **printers = kdk_printer_get_available_list();
        while (printers[index])
        {
            printf("%zd: %s, index + 1, printers[index]);

            //取消当前打印机所有打印任务

            //获取url对应的文件名
            char *url = "http://www.cztouch.com/upfiles/soft/testpdf.pdf";
            int res = -1;
            char *filename = kdk_printer_get_filename(url); //从完整路径名中解析出文件名称，例如：/home/test/abc.txt,解析完成后为abc.txt
            printf("filename = %s, filename);

            //设置打印参数
            kdk_printer_set_options(2, "A4", "lrtb", "two-sided-long-edge");

            //下载
            res = kdk_printer_print_download_remote_file(url, filename);
            printf("[%s] res = %d, __FUNCTION__, res);
            printf("[%s] filepath = %s, __FUNCTION__, filename);

            //打印
            int job_id = kdk_printer_print_local_file(printers[index], filename);
            if (job_id == 0)
            {
                //打印失败

            }
            else
            {
                //打印成功，等待一会获取任务状态
                sleep(10);
                int status = kdk_printer_get_job_status(printers[index], job_id);
            }

            index++;
            free(filename);
        }
        kdk_printer_freeall(printers);
        return 0;
