Zebra打印机在TCP/IP上返回短TID而不是完整的24个字符

Question

我使用python通过TCP/IP与zebra R600(最新固件)打印机通信，以发送ZPL，该ZPL将从标签读取TID并使用ZPL ^HV存储在文件中。

我的问题是每80个标签左右(随机)我从打印机得到一个更短的TID(示例如下)

我试图改变打印机缓存，但它似乎没有任何效果，问题是相当随机的，短输出是从一个正常的标签。有什么建议吗?

我代码:

#!/usr/bin/env python
import socket
import os.path
from os import rename
global data
global count
count = 0

def writeTID(tid):  
    f = open("UID_list.txt",'a')
    f.write(str(tid) + "n")
    f.close()

def Read_TID(quantity):
    global count
    f = open("UID_list.txt",'a')
    s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    s.connect((TCP_IP, TCP_PORT))
    for x in range(0,int(quantity)):
        zpl = """
        ^XA
        ^RSB,B30,236,3,N
        ^RR10

        """
        print "Tag number:"+str(x+1)
        s.send(str(zpl))
        data = s.recv(BUFFER_SIZE)
        print "Received data:", data
        f.write(str(data) + "n")
        if (len(data)<24):
            count+=1
    print "nnumber of errors: "+str(count)
    s.close()
    f.close()

print ("tttn------------------n")
while True :
    if os.path.isfile("UID_list.txt"):
        num_lines = sum(1 for line in open("UID_list.txt"))
        print("nYou have "+str(num_lines)+" labels in corrent roll")
    print("n1:Start or continue rolln2:Finish rolln")
    selected = raw_input("tPlease select an option: ")
    if selected =="1":
        add_number = raw_input("How many labels to manufacture?n ")
        Read_TID(add_number)
    elif selected =="2":
        roll_number = raw_input("What is the roll number?n ")
        rename("UID_list.txt","UID_list_Roll_"+str(roll_number)+".txt")

Answer 1

增加了s.s send(str(zpl))和s.s recv(BUFFER_SIZE)之间的延迟，该延迟等于打印机弹出标签的时间(time.sleep(1.5))
