Probably you already damaged the drum or fuser coating. Direct laser printing will not work easily for several reason, many discussed here at great length before. The only possible semi-direct laser printing method i can imagine was not tried yet as far as i know. Basically it involves an intermediate silicone roller picking up the image from the drum to transfer it to a heated board passing below. I have not found a theoretical reason yet why it would not work but that doesn't mean much.
