Hello! I am trying to make an .exe with this code and cx_freeze package. The .exe is made with cxfreeze-quickstart.exe execution. But then when I try to open this PDFprinter.exe it throws an error "no module named win32". I am thinking this is somehow related the pywin32 package..
I just wonder, have you tried to make an .exe executable program with this code? Maybe by any other way instead of cx_freeze?
Thank You! And Thanks for great code!

it is giving me error like this please help : Exception in Tkinter callback
Traceback (most recent call last):
File "D:\Users\Lucifer\AppData\Local\Programs\Python\Python37-32\lib\tkinter_init_.py", line 1702, in call

File "D:/Users/Lucifer/Python/letsdoitprint.py", line 52, in PrintAction
pHandle = win32print.OpenPrinter(_printer.get(), PRINTER_DEFAULTS)
pywintypes.error: (5, 'OpenPrinter', 'Access is denied.'), Although I have Installed the Printer and also the drivers required to do printing.
