Python 調用打印機API - APISample Python 標簽打印范例代碼,,Python 打印, Python 實現打印,Python調用打印機, Python 打印API,Python 打印報表,Python 標簽打印,Python 單據打印 ,CCPrintingAPI , Python 打印機調用范例代碼，Python 標簽打印，條碼，二維碼標簽，Python 單據打印，很容易集成。

1. 引用 CCPrintingApiNet.dll

引用CCPrintingApiNet.dll后，即可使用API的相關方法，進行設置和打印操作。

clr.AddReference("CCPrintingApiNet")
from Chicore import CCPrintingApiNet
from Chicore import ConfigPrintSettings

#獲取所有打印機
getprinters(m_OpenId,m_Tokens,Action[Object](printers_callback))
#打印
printex(m_OpenId,m_Tokens,Action[Object](print_callback))
#獲取HID
gethid(m_OpenId,m_Tokens,Action[Object](hid_callback))

2. 獲取打印機

獲取計算機上所有打印機, 打印時，指定該列表的打印機名稱。如果能確保打印機名稱不變，該操作也可省去。

#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

進行相關參數設置后（指定打印機，設置模板，設置打印數據），將指令通過API傳給打印機。

#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]))

#執行打印 
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"
    #傳入數據
    newprtdata = "987650002;CCPrintingAPI;測試產品 API新接口"
    prtdata = "[{sku:'OBJ100001',name:'測試1',kw:'D12-1',bh:'RKD123451'},{sku:'OBJ100002',name:'測試2',kw:'D12-2',bh:'RKD123452'}]"
    cfgData.PrintDataType = 1
    cfgData.PrintData = prtdata
    CCPrintingApi.ExcuteEx(cfgData,callback)

4. 讀取客戶端HID

讀取安裝CCPrintingAPI的客戶端計算機HID,該HID可以用來標識計算機。該方法，根據需要使用。

#獲取HID
def hid_callback(arg):
    status = arg.Status
    arg0 = arg.Message
    sessionid = arg.SessionId
    print("Excute Status: {:d}, SessionId:{:s}".format(status, sessionid))
    if arg0 == None:
        return
    if status == 1 :
        print("{:s}:{:s}".format(arg0[0],arg0[1]))
    
def gethid(openid,token,callback):
    cfgData = ConfigPrintSettings()
    cfgData.XAction = "HID"
    cfgData.XOpenId = openid
    cfgData.XTokens = token
    CCPrintingApi.ExcuteEx(cfgData,callback)
