HP Color LaserJet CM4730 MFP Printer Firmware 50.343.3

IMPORTANT NOTE:

“This firmware version installs code signing verification functionality. Firmware signed by HP guarantees the integrity and authenticity of the code; meaning that the firmware was produced by HP (authenticity) and that the firmware has not been altered in any way (integrity). “

ATTENTION:

Once this firmware has been applied to your printer or multifunction device it CANNOT BE DOWNGRADED to a previous version of firmware.

Enhancements:
- Added support for the J&H licensing method.
- Firmware now has the Report a problem feature enabled only through HP. Allows users to request for support from MPS via email.
- Job Logging feature added.
- Upgraded the font library to version 7.3.
- Firmware now includes the ability to lock the send to network folder address using the “Edit the Send to Folder Path” item in the EWS Authentication Manager.
- Security issue CVE-2014-3566 – SSLv3 POODLE (Padding Oracle on Downgraded Legacy Encryption) Vulnerability has been addressed.
- Firmware now includes the ability to disable the fax module in the EWS. 

Fixes:

- Webkit tries to use TCP connections that have been closed by the remote side, which ends up with several TCP retransmissions.
- Certain fonts are not printing correctly after firmware upgrade to the version 13.3.5.
- Unable to delete the Private Jobs from WJA.
- Error 49.4c02 is seen when accessing the Job status from control panel, when printing a Job having filename more than 20 Japanese characters.
- Send to Network folder creates intermittent 0KB pdf files within dfs environment.
- Unable to resolve specified Send to Network folder path due to CIFS timeout.
- No new updates.
- Fax forwarded to email have file format of PDF version 1.1 which cannot be viewed in the newer versions of PDF reader.
- Default billing code field has some invalid characters thus not allowing users to input the billing code.
- If a DHCP server responds to a REQUEST with a NAK, the server will be ignored by the Jetdirect Client until it is rebooted. The NAK is sent by a server if the client requests an address that is not supported by the server; this happens if the client has moved to a new network and attempts to renew an address from the old network.
- Implemented DHCP option 144.
- Short default TTL value caused the product to use DNS lookup cache and overlook server IP address changes. This fix involved using the TTL value provided by the DNS server instead of a fixed default.
- Certificates signed with an MD5 hash are no longer accepted by the product and many popular applications. The product will automatically replace an internally generated self-signed MD5 identity certificate with a new self-signed SHA256 identity certificate so that it maintains compatibility with current versions of popular applications.
- Fixed a problem where an "Invalid Credentials" error is returned for SNMPv3 I/O attempts.

About Printer Firmware:

Applying a newer firmware version than the one already installed on your unit can bring various enhancements, include workarounds for diverse problems encountered by the device, and improve or add newly developed features.

On the other hand, downgrading the firmware version can recover the device’s functionality in the event of a software update either turning up faulty or causing the unit’s overall performance to drop. However, bear in mind that applying an older firmware isn’t recommended and might not always be possible.

When it comes to the update steps, due to the large variety of devices and numerous ways for installing a new firmware, it is recommended that you carefully read and understand the upgrade steps, and consider applying a different firmware only when you have familiarized yourself with the update method.

As the installation process is most of the times quite risky, this step should be taken by users that have the ability to successfully complete the update; regular users may initiate it at their own risk. Moreover, it’s best that this task be performed in a steady power environment such as the one ensured by a UPS unit.

Therefore, if you consider applying this release, hit the download button, take into account all the aforementioned aspects, and update the device’s firmware. Also make sure you constantly check with our website to ensure that you don’t miss a single new release.
