Question

Googled a lot but returned empty hand..

I would like to know if anyone used AddPrinterDriver or AddPrinterDriverEx API using winspool.drv in c#.

Please provide me the code that does initialising and using this API Call.

Urgent..!!

Answer 1

I have been working on this same issue for some time, and have something to start with, though I am still running into issues. I believe my real issue now is creating the list of dependent files properly. Perhaps you know how to fill in these blanks for me?

Thanks,
Stephen
