python - 使用 win32print + cx_Freeze 时，打印指令不起作用且不会产生任何错误

Question

Windows 10 (x64)Python 3.6.3cx_Freeze 5.1.1pypiwin32 223/pywin32 224

我制作了一个用于打印的模块，该模块在作为脚本启动时工作正常。一旦通过 cx_Freeze，打印命令将无法工作且不会产生任何错误消息。这是我用于创建构建的 setup.py (作者:python setup.py build)

# -*- coding: utf-8 -*-
import sys,os
from cx_Freeze import setup, Executable

PythonPath = os.path.split(sys.executable)[0] #get python path

includes = []

excludes = []

packages = ["win32print"]

includefiles = ["OptiWeb.ico"]

options = {"includes": includes,
           "excludes": excludes,
           "packages": packages,
           "include_files": includefiles,
           "optimize":2
           }

base=None

if sys.platform == 'win32':
    base = "Win32GUI"
    options["include_msvcr"] = True


executables = [Executable(script="OptiPrint.py",base=base,icon="Optiweb.ico")]

setup(name = "OptiPrint",options = {"build_exe": options},version = "1.0",author = "ND",description = "print test",executables = executables)

现在我的打印代码:

# coding: utf8

import win32print

class ZPLLabel(object):
    def __init__(self, printerName):
        self.printerName = printerName
        self.printerDevice = win32print.OpenPrinter(self.printerName)
        self.job = win32print.StartDocPrinter(self.printerDevice, 1, ("Etiquette", None, "RAW"))
        self.eraseAll()
        self.defineFormat()

    def eraseAll(self):
        win32print.StartPagePrinter(self.printerDevice)
        str2print="~JA"
        win32print.WritePrinter(self.printerDevice, str2print.encode("utf8")) #écrit le format d'étiquette
        win32print.EndPagePrinter(self.printerDevice) # indique la fin de ce qu'il y a à imprimer
        self.printerDevice.close() # ferme le canal d'impression et déclenche l'impression de ce qui précède
        #del self.job    
        self.printerDevice=win32print.OpenPrinter(self.printerName)
        self.job = win32print.StartDocPrinter(self.printerDevice, 1, ("Etiquette", None, "RAW"))

    def defineFormat(self):
        margeLeft = 150

        del self.job

def newPrintLabel():
    zpl = ZPLLabel('Zebra ZP 450 CTP')
    zpl.printLabel("20009999", "1035691", "Harnais Energy TWIN ss porte outil L/XL",
                       "90008318", "SA/SANGLE NOIRE 20 MM", 35, "0.38m", "Bavaroise réglable")
    zpl.endLabel()

if __name__ == '__main__':
    app = newPrintLabel()

我想，缺少一些包或 dll，无法使其在卡住时运行。我尝试添加 win32api、win32com 但它不会改变结果。

感谢您的帮助，我们非常欢迎。

尝试使用 win32ui 和 win32con，如 python win32print not printing 的答案中所做的那样.

在这种情况下，您还应该保留原始问题中定义的base(关于我对您问题的评论)。
