Subject: unlocking HP printer
Hello.
I have an HP LaserJet 4mPlus that was inherited from a PC network.
Whenever I try to reconfigure it from the control panel, I get a "MENUS
LOCKED" message, and I can't get to the menus. I couldn't find Menu
Locking in the HP manuals or on their web site. Anyonw know how to
unlock this?
Thanks.

I did not state in the original message that I was purely working on
serial and parallel connections. There was no way to use telnet to
contact the printer.
The winning entry :

You can do that by reset the EPROM of the printer. You need to program
it completly.
Procedure :-
Go to Test Menu and print a test page that has all the information of
the current setup.
Power off the printer.
Press the on-line button and power-on the printer. It will reset all
parameter to default.
Use the menu re-program it.
DON'T LET YOUR END-USER KNOW THIS TRICK.....

About your "Menu locked" HP printer: Your should be able to telnet to
it through your network. I don't remember just exactly what the commands are
but you can type "?" to get help. There are provisions for password
protecting which you may need to read about in your manual. Best of luck
and if you find anyplace that this is documented well, please pass that info
back.

if this printer is on the network with IP#
try telnet - by default there is not password

Your HP printer has been locked with the "jetadmin" software. You must
use jetadmin to unlock it. As long as you do this as root, I don't think
the program will even request the password from you, so if you don't have
the password, you can reset it this way.

You can use this PJL Job to configure the Control Panel Locking.
JOB PASSWORD is in the range from 0 to 65535
If you don't know it the only way I know is to try it.
