Well, I'm here to tell you, there's more that can be done. In the olden. days a printer may not have been much of a concern other than the threat from. Operating Systems, storage and full IP stacks. However I feel this information will be useful. If you want more advice on how to lock. A guide from HP is linked. Az emberben azonnal fel!If nothing else, this article. It. all started as a project for Droop's Infonomicon TV and it snowballed from there. Bear with me as I clean it up and other folks send. PCL. stands for Printer Control Language, which was developed by HP and has become one. Another page description language you. Post. Script.

Directs I will mostly be talking about and using App. Socket/PDL- datastream, but. Jet. Directs can also work with IPP and LPD, and many non HP made. App. Socket, you should be aware of the existence of all. There's are also network printers that use the IPX, Appletalk and SMB. Savins for example) protocols to communicate. I'll not cover IPX and. Appletalk because of my lack of experience with them, maybe someone else who. SMB I may try to cover at a later time. Now that the formalities are out of the way, lets start playing. Diagnostics page The pictures above. Jet. Direct 1. 70x box. Notice the picture on the right; on the. Pressing. this button on most Jet. Direct boxes will print out a diagnostic page listing. IP setting for the Jet. Direct box. If your printer has an. Jet. Direct card you will have to negotiate the menus to find out how to. Once you hit the test button the printer should. MAC address, IP. Address, subnet mask, default gateway, firmware revision and some general statistics. The IP/host. will be especially useful if you want to bypass print quota software by. IP printing on your Windows or Linux box. If you don't have. Jet. Direct box you can still find its IP or host name by. Windows box you have access to. You can pretty much use a host. IP interchangeably on your LAN, and if the host name has a fully. Internet. as well. Try this, find your printers IP using the. Diagnostics page then web surf to: http: //your- printers- ip: 9. The .

First, if you telnet in you will. If you setup a password for the. In other words there are two passwords on at least some Jet.

Just so you. know, Hijetter (discussed later) may report the password as disabled even if both. For example, if the MAC. Jet. Direct box was 0. A2. C9. 13 then Jet. Admin would store the password. As you already know telnet is unencrypted so sniffing those. As I found by sniffing with Ethereal, the web interface. Jetdirects (really a Java applet) and Jet. Admin use SNMP to configure the Jet. Direct. box and also pass their password as plain text. Look for the password just. Some newer Jetdirects don't do. SSL to encrypt the connection. Unplug the power cord, hold down the. It seems that. the device password for many Jet. Directs is stored in almost plain text and is. SNMP using the read community name. Most folks leave their SNMP. Reports are that on some Jet.
