在win32下操作printer:
1）import win32print
2） 获得默认打印机名：
>>> win32print.GetDefaultPrinter()
'Canon LBP-800'
3）打开一个指定的打印机并获得其句柄
>>> handle = win32print.OpenPrinter('Canon LBP-800')
4）获得一个指定的打印机句柄所对应的打印机的信息
>>> win32print.GetPrinter(handle)
(None, 'Canon LBP-800', '', 'LPT1:', 'Canon LBP-800', '', '', None, '', 'W
inPrint', 'RAW', '', None, 2624, 1, 0, 0, 0, 0, 0, 0)
5）关闭打印机
>>> win32print.ClosePrinter(handle)
5）枚举打印机,呵呵，看看MSDN，琢磨一下flag对应的几个位
>>> win32print.EnumPrinters(2)
