从蟒蛇窗口print tutorial:

import win32api 
import win32print 

def parts_list(): 
    a = ["CPU,$150.00","RAM ,$120.00","DVD drive $89.00","Hard Disk Drive,$189.99"] 
    with open('printfile.txt', 'w') as f: 
     for line in a: 
      f.write(line) 
    print_windows('printfile.txt') 

def print_windows(filename): 
    win32api.ShellExecute(0, "print", filename, '/d:"%s"' % winn32print.GetDefaultPrinter(),".", 0) 

def main(): 
    parts_list() 

if __name__ == '__main__': 
    main()
