I'm having a hard time understanding what I'm doing wrong in my code.
I'm only a beginner at programming, but so far enjoying it.

I'm planning to build something that will add all our custom paper sizes to the printer spooler of a computer.
In this code first trying to figure out to add a single paper size. When this works I want to expand it to more.

import win32print

pHandle = win32print.GetDefaultPrinter() 
printer = win32print.OpenPrinter(pHandle)

print(pHandle)
print(printer)

Test=({'Flags': 2, 'Name': 'Test', 'Size': {'cx': 215900, 'cy': 279400}, 'ImageableArea': {'left': 0, 'top': 0, 'right': 215900, 'bottom': 279400}})
win32print.AddForm(0, Test)
win32print.ClosePrinter(printer)

I'm getting the following error:

Error:
Traceback (most recent call last):
  File "C:\Work\I-Commit\Python\Temp.py", line 10, in <module>
    win32print.AddForm(0, Test)
pywintypes.error: (6, 'AddForm', 'De ingang is ongeldig.')

So far I've looked at the following:
http://timgolden.me.uk/pywin32-docs/win3..._meth.html
And tried to google the error, but I'm not finding anything that will help me forward.

Can somebody explain this error and point me in the right direction?

There is so little available on this package.
Might I suggest https://pypi.org/project/win32printing/ instead
