        from Chicore import CCPrintingApiNet
        from Chicore import ConfigPrintSettings
        
        #获取所有打印机
        getprinters(m_OpenId,m_Tokens,Action[Object](printers_callback))
        #打印
        printex(m_OpenId,m_Tokens,Action[Object](print_callback))

2. 获取打印机

获取计算机上所有打印机, 打印时，指定该列表的打印机名称。如果能确保打印机名称不变，该操作也可省去。

#获取打印机回调
        def printers_callback(arg):
            status = arg.Status
            arg0 = arg.Message
            sessionid = arg.SessionId
            print("Excute Status: {:d}, SessionId:{:s}".format(status, sessionid))
            if arg0 == None:
                return
            #获取成功，显示所有打印机
            if status == 1 :
                for i in range(1,len(arg0)):
                    print(arg0[i])
        #获取打印机    
        def getprinters(openid,token,callback):
            cfgData = ConfigPrintSettings()
            cfgData.XAction = "Printers"
            cfgData.XOpenId = openid
            cfgData.XTokens = token
            CCPrintingApi.ExcuteEx(cfgData,callback)

3. 打印

进行相关参数设置后（指定打印机，设置模板，设置打印数据），将指令通过API传给打印机。

#打印回调
        def print_callback(arg):
            status = arg.Status
            arg0 = arg.Message
            sessionid = arg.SessionId
            print("Excute Status: {:d}, SessionId:{:s}".format(status, sessionid))
            if arg0 == None:
                return
           #打印成功
            if status == 1 :
                print("{:s}:{:s}".format(arg0[0],arg0[1]))
        
        #执行打印 
        def printex(openid,token,callback):
            cfgData = ConfigPrintSettings()
            cfgData.XAction = "Print"
            cfgData.XOpenId = openid
            cfgData.XTokens = token
            cfgData.PrinterName = "Honeywell PC42t (203 dpi) - DP"
        
            #使用模板
            cfgData.TemplateMode = 1
            cfgData.TemplateURL = "http://img.51321.cn/web/chicore/VPrinting/API"
            cfgData.TemplateName ="183601-70X40.Lblx"
            #传入数据
            newprtdata = "987650002;CCPrintingAPI;测试产品 API新接口"
            prtdata = "[{sku:'OBJ100001',name:'测试1',kw:'D12-1',bh:'RKD123451'},{sku:'OBJ100002',name:'测试2',kw:'D12-2',bh:'RKD123452'}]"
            cfgData.PrintDataType = 1
            cfgData.PrintData = prtdata
            CCPrintingApi.ExcuteEx(cfgData,callback)
