EXAMPLES

#include "libkyprinter.h"
#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: %s0, index + 1, printers[index]);
        //取消当前打印机所有打印任务
        kdk_printer_cancel_all_jobs(printers[index]);
        //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 = %s0, 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 = %d0, __FUNCTION__, res);
        printf("[%s] filepath = %s0, __FUNCTION__, filename);
        //打印
        int job_id = kdk_printer_print_local_file(printers[index], filename);
