You're getting warmer. A firmware upgrade is what you're looking for. Go to: http://hpcc923.external.hp.com/cposupport/indexes1/firmwars.html This page has the firmware upgrade images, plus the HP Download Manager tool that you use to actually install it. Once you upgrade to the latest firmware you'll find that the banner command (and some other new stuff) is available. It's not, however, quite so simple. In order for this process to work, you must have configured the SNMP-Set community string. To do this, you must create a tftp'able configuration file that contains at least this setting. Then, you must configure your bootp server (you _are_ using bootp, right!?!) so that the entry for the printer has the vendor extended option T144 set to the tftp path of the file. As an example, my config file looks like this # HP LJ config file location: Young, Math/CS Dept., PC Lab contact: Information Technology Services, x3803, its-help@enc.edu # get-community-name: fooBar set-community-name: fooBar old-idle-mode: off banner: 0 # telnet-disable: 1 Note, I have the get-community-name setting commented out. This is necessary because the Download Manager program allows you to specify the set-community-name that it should use, but not the get-community-name. Leaving its commented out as shown causes the printer to respond to any and all SNMP get requests, which is the only way that I could get the download process to happen. Once you're done with the upgrade, you can, of course, set the get-string to something specific. Here's a snippet from my dhcpd.conf file (I use the ISC's dhcpd for dhcpd _and_ bootp service) that shows the needed parameters to load the config file: host mtcslj4a.ac.enc.edu { hardware ethernet 08:00:09:77:1A:A8; next-server delta.enc.edu; option option-144 "hplj.cfg"; fixed-address mtcslj4a.ac.enc.edu; } This can be done just as easily with the "standard" bootp/bootptab. You should know that the config file can contain a number of other settings. For somewhat useful docs on this (but without proper syntax), see ftp://ftp.hp.com/pub/networking/support_doc/bpj02835.asc and ftp://ftp.hp.com/pub/networking/support_doc/bpj02836.asc To see the true syntax of the config file options, download the HP Jetadmin software package for HP-UX and look for the file */examples/tftp.conf See also the file bootptab in the same dir. It's pretty nifty stuff, though one shouldn't have to dig quite so hard to find these details, and the HP engineer should have known that you needed to upgrade your firmware.
