Nmap Development: Nmap 3.90 and JetDirects

["Crenshaw, Adrian D" <adrian () ius edu>]

I’m writing an article on hacking network printers and this topic came up. One problem with Nmap scanning port 9100 
with version detection turned on is you get garbage print jobs with text like:

GET / HTTP/1.0
OPTIONS / HTTP/1.0
OPTIONS / RTSP/1.0

That corresponds to the probes Nmap is sending to try and tell what service is running on that port. Or at least you 
use to, a friend said he tested with 3.90 and that no longer happens, at least on his JetDirect. Was something changed 
with 3.90 to fix the JetDirect port 9100 problems? 

Thanks,
Adrian
