国产麒麟系统ARM64直接使用pip安装pycups安装失败，需要先安装系统的依赖：
sudo apt install libcups2-dev python3-dev python3-setuptools这点在pycups官网中有说明，一直以为直接安装就行，折腾了很久，https://github.com/OpenPrinting/pycups
Packages needed for compilation (default package names are from Fedora, Ubuntu names are in the brackets
if they differ from Fedora):
- gcc
- cups-devel (libcups2-dev)
- python3-devel (python3-dev)
- (since Python 3.12) python3-setuptools
Please install them before compiling PyCUPS.
