Hacking Network Printers-Mostly HP JetDirects, but a little info on the Ricoh Savins
Hacking Network Printers
(Mostly HP JetDirects, but a little info on the Ricoh Savins)
Here is my little article on how network printers like JetDirects and Ricoh Savins can be hacked. I've attached it as a PDF since it has too many graphics to make posting it with the forum software practical.
The web version can be found at:

I plan to do updates as needed, so please give me some feed back. My last few posts haven’t got many replies, I’d like to hear from you all. Here is the table of contents to give you an idea about the subject matter:

I don't have time to read the whole thing now, but a copy will take residence on my thumb drive so I can read it whenever I have some free time. I heard about people hacking printers with JetDirect, and I've always wanted to try it out myself.
