如何用python写程序设置当前打印机为默认打印机_从Python打印到标准打印机？

Is there a reasonably standard and cross platform way to print text (or even PS/PDF) to the system defined printer?

Assuming CPython here, not something clever like using Jython and the Java printing API.

解决方案

Unfortunately, there is no standard way to print using Python on all platforms. So you'll need to write your own wrapper function to print.

You need to detect the OS your program is running on, then:

For Linux -

import subprocess

lpr = subprocess.Popen("/usr/bin/lpr", stdin=subprocess.PIPE)

lpr.stdin.write(your_data_here)
