joker Posted May 3, 2011 Share Posted May 3, 2011 (edited) I read about the HP network printer hacks, but I have come across many Dell network printers and I want to test out how vulnerable they are. To start things off, I performed a port scan: Not shown: 971 closed ports PORT STATE SERVICE 21/tcp open ftp 79/tcp open finger 80/tcp open http 161/tcp filtered snmp 179/tcp filtered bgp 515/tcp open printer 631/tcp open ipp 1022/tcp filtered unknown 1035/tcp filtered multidropper 1057/tcp filtered unknown 1126/tcp filtered unknown 1213/tcp filtered unknown 1233/tcp filtered unknown 1862/tcp filtered unknown 3878/tcp filtered unknown 5000/tcp open upnp 5001/tcp open commplex-link 5004/tcp filtered unknown 5566/tcp filtered unknown 8000/tcp open http-alt 8099/tcp filtered unknown 9000/tcp open cslistener 9100/tcp open jetdirect 9200/tcp open wap-wsp 9500/tcp open unknown 9595/tcp filtered pds 10000/tcp open snet-sensor-mgmt 27356/tcp filtered unknown 49161/tcp filtered unknown I have to figure out how to change the lcd display. I wonder if there are PJL commands Any Ideas? Edited May 3, 2011 by joker Quote Link to comment Share on other sites More sharing options...
Infiltrator Posted May 3, 2011 Share Posted May 3, 2011 According to this text, this Dell printer supports post script drivers, which supports PJL http://en.community.dell.com/support-forums/peripherals/f/3528/t/16934383.aspx Quote Link to comment Share on other sites More sharing options...

joker Posted May 22, 2011 Author Share Posted May 22, 2011 all network printers that have port 9100 will support PJL to change display the command is: @PJL RDYMSG DISPLAY = "message" [<CR>]<LF> if that does not work then try @PJL JOB DISPLAY = "message" [<CR>]<LF> this command will change display and make the printer go offline @PJL OPMSG DISPLAY = "message" [<CR>]<LF> to use just telnet to the port Quote Link to comment Share on other sites More sharing options...
