In order to appear as a normal printer, you have to develop a printer driver. That's going to require the use of the DDK, the Driver Development Kit. You can get this from Microsoft for just shipping and handling (about US$20). It includes all of the compilers, include files, and libraries you would need. It also includes a number of sample drivers.


Drivers cannot be written in Python. The device driver interfaces are all C-style APIs.

(Well, theoretically, I supposed you could write a C DLL that thunked to a Python service, but that would be more trouble than writing it in C or C++ to begin with.)
