2. 獲取打印機

獲取計(jì)算(suàn)機上(shàng)所有(yǒu)打印機, 打印時(shí)，指定該列表的打印機名稱。如果能确保打印機名稱不變，該操作(zuò)也可(kě)省去。

#獲取打印機回調
        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
            #獲取成功，顯示所有(yǒu)打印機
            if status == 1 :
                for i in range(1,len(arg0)):
                    print(arg0[i])
        #獲取打印機    
        def getprinters(openid,token,callback):
            cfgData = ConfigPrintSettings()
            cfgData.XAction = "Printers"
            cfgData.XOpenId = openid
            cfgData.XTokens = token
            CCPrintingApi.ExcuteEx(cfgData,callback)

3. 打印

進行(xíng)相關參數(shù)設置後（指定打印機，設置模闆，設置打印數(shù)據），将指令通(tōng)過API傳給打印機。



#構建模闆
def GetSelfDraw():
    vSelfdraw = CCSelfdraw()
    #數(shù)據字段
    FieldNames = { "ImageUrl" };
    vSelfdraw.XDataBase.SetFieldNames(FieldNames)

    vSelfdraw.XPageSettings.PrinterPaperAutoSet = 1
    vSelfdraw.XPageSettings.UseQuickSetTool = 1
    #标簽尺寸
    vSelfdraw.XLabelDetail.Width = 70;
    vSelfdraw.XLabelDetail.Height = 50;
    vSelfdraw.XLabelDetail.ColumnSpan = 2;
    vSelfdraw.XLabelDetail.RowSpan = 2;

    #圖片設置
    vImageElement = ImageElement()
    vImageElement.Name = "Image1";
    vImageElement.X = 0;
    vImageElement.Y = 0;
    vImageElement.Width = 70;
    vImageElement.Height = 50;
    vImageElement.IsBind = 1;
    vImageElement.BindField = "ImageUrl";
    vImageElement.KeepRatio = 1;
    vImageElement.ImageColor = 2;
    vSelfdraw.XImageElements.Add(vImageElement);
    return vSelfdraw.ToString();


#打印回調
        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]))

    #傳入數(shù)據
