Upgrading Firmware for HP Jetdirect Devices versus Printer Devices
Upgrading rmware on HP Jetdirect devices versus printing devices is similar but not identical. HP Jetdirect
rmware updates are done by contacting the device through SNMP and directing it to perform an update by
obtaining the updated rmware from a TFTP service that is started on the HP Web Jetadmin server.
HP Web Jetadmin uses the standard port number for the TFTP server (port 69) that may get blocked by rewall
software on the system hosting HP Web Jetadmin software. Once the update action is started, the device
performs actions against the image le on the TFTP server until the whole image le is obtained. The actual
update action is performed by the HP Jetdirect device itself.
Printer rmware updates are done by HP Web Jetadmin sending the RFU image le to the printer in the same
way a print job would be sent. This print-le action is done via port 9100 on the printer. Once the printer receives
the job, it recognizes it as an update and then launches internal processes that perform the actual update.
HP Web Jetadmin is used strictly as a le send agent in the case of printer rmware updates.
NOTE: If an HP Jetdirect rmware upgrade is launched during a large print job, the job will not nish processing
and will need to be restarted by the user.
Firmware Repository
The rst step in rmware updates is to nd available images. Images exist on www.hp.com and can be accessed
in two ways:
●
HP Web Jetadmin can contact www.hp.com and display available images for you.
●
You can manually obtain and import image les to HP Web Jetadmin.
In both cases, the goal is to get the desired image onto the HP Web Jetadmin host so that it can be used for
updating. This image will be shown on the Firmware Repository page.
NOTE: For more information about qualifying rmware and the Firmware Repository, see Qualifying Firmware
on page 210.
View the Firmware Repository
You can view the rmware images that HP Web Jetadmin uses on the Firmware > Repository page. This page
displays the following:
●
Version of the rmware.
●
Date of the version.
●
Whether or not the image is local.
●
Languages that the rmware supports. All available is displayed for images that do not support languages
packs.
●
Device models that the rmware upgrade supports.
Use the following steps to view the Firmware Repository:
1. In the left navigation pane, expand Firmware and click Firmware Repository.
2. The available rmware upgrades are listed on the Firmware Repository page.
