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) 

         ((8388608, '\264\253\325\346,Windows NT Fax Driver,', '\264\253\325\346',  

''), (8388608, 'FinePrint 2000,FinePrint 2000,', 'FinePrint 2000', ''), (838

         >>> win32print.EnumPrinters(8)
