How reproducible:
进入AnolisOS8的docker容器执行以下指令

Steps to Reproduce:
1.yum install -y cups-client
2.lpstat -t
3.

Actual results:
returncode: 1
stdout: scheduler is not running
no system default destination

stderr: lpstat: Bad file descriptor
lpstat: Bad file descriptor
lpstat: Bad file descriptor
lpstat: Bad file descriptor
lpstat: Bad file descriptor

在 anolis8 上，当前使用 2.2.6 版本的 cups 
使用 lpstat -t 显示打印系统的全面状态信息，结果如上：当系统中没有添加任何默认打印机时返回值非0，此行为上游 cups 2.2.6 版本默认行为。对比其他同样集成 2.2.6 版本 cups 的操作系统系统，行为一致，所以非 anolis8 缺陷，是上游默认设计。
在 anolis23 上，当前使用 2.4.10 版本的 cups，使用上游 2.4.10 版本源码编译测试后，返回值为0，此为上游默认设计。
[root@test cups-2.4.10]# /root/cups-2.4.10/systemv/lpstat -t
scheduler is not running
[root@test cups-2.4.10]# echo $?
0
[root@test cups-2.4.10]# 

所以anolis8和anolis23上此差异源于上游差异，
具体版本差异请参考上游变化
