您好

如果目前 打印机可以能满足日常办公要求,可以不升级固件。

升级固件后一般都不可降级,打印机不会因为升级固件后功能增多,固件一般是修复打印机存在的一些隐性漏洞的。

HP m551dn 彩色打印机最新3.91版固件主要有哪些变动?

ENHANCEMENTS: Base: ➢ The Backup and Restore feature has been expanded to include JDI settings. Additionally, this feature has been expanded to allow creating a backup file and restoring that file to another device of the same model and firmware version as the backup file. ➢ Added support for "Any Size/Any Type" in cassette trays. ➢ This feature increases the number of allowed PIN users in the device's local address book; from 1000 to 2000. ➢ Optimized JPEG decompression library improves performance of print jobs with JPEG compressed images ➢ A new option has been added to delete the temporary jobs after 3 days. ➢ Error code “42.B0.01” will not be displayed in the event log for end customers. ➢ Added new feature to allow PCL 6 to suppress blank pages. Previously this feature was only available with PCL5, now this functionality is also available with PCL6. ➢ Changes in power management to meet new Blue Angel regulations. Security/Authentication: ➢ Users now have the ability to disable printing from Help. ➢ Added two new features to improve the private and usability of retrieving stored jobs from the "Retrieve from Device Memory" application. Administrators can define what users first see when entering the "Retrieve from Device Memory" application. The default behavior has not changed, but administrators have a new setting in the embedded web server under "Security" [Tab] -> "Protect Stored Data" [Menu] -> "Managed Stored Jobs" [Section] called "Behavior when users are authenticated. If "Assist users to their jobs" is selected, users entering the application will immediately see their jobs provided a folder exists by their username (default behavior in the print driver when sending jobs) but can navigate back to the list of folders with jobs. Administrators will also note a new permission that is not activated by default in the embedded web server under "Security" [Tab] -> "Access Control" [Menu] -> "Sign In and Permission Policies" [Section] -> "Open from Device Memory application" [Control Panel Permission] for "Other Users' Jobs and Folders". If removing the permissions (e.g. for "Guest" and "Device User") a regular user will only be able to see their or guest jobs. If at the folder view they will only be able to see folders with at least one of their own jobs or a guest job within it except for the special folders like "Untitled" & "Stored Faxes". These two features can be used together to optimize the privacy & usability when users retrieve their stored jobs. ➢ Allow for nested group behavior on the EWS: Security>Access Control>Windows Setup. Nested AD groups may be configured to inherit parent permissions. ➢ Allows for authentication at devices using AD credentials instead of local device credentials via Web Jet admin. ➢ This firmware provides compatible HP and 3rd party solution software the ability to establish HTTPs communications through the Jetdirect networking interface. The protocol and encryption parameters for these solutions are now configured using the Jetdirect networking settings, allowing access to updated Jetdirect protocols and encryption. This option is available to HP and 3rd party solutions using the HttpWebRequest Class connection methods. ➢ This firmware addresses the following security issues: CVE-2005-4900– SHA-1 is not collision resistant, allowing for context-dependent spoofing attacks. Cipher suites containing the SHA-1 hashing algorithm can now be disabled by setting Encryption Strength to “High” within the “Mgmt. Protocols” page under the EWS Networking tab. These cipher suites will remain enabled/active if Encryption Strength is set to either “Medium” or “Low”. Note: For devices with Encryption Strength set to “High”, after installing this firmware the Encryption Strength setting will be changed to “Medium” to allow continued access to SHA-1 cipher suites. Embedded JetDirect: ➢ No New Updates. FIXES: Base: ➢ You may see a 49.00.FF error while performing a Direct TIFF print job. ➢ Setting Legacy resolution to 300 x 300 would not be retained after a power cycle. ➢ Print job size of 400mb or more not getting stored on the device disk memory. ➢ Disk resident fonts are not persistent after a power cycle.  Paper type is displayed incorrectly on control panel when using Chinese. ➢ Wrong translation of control panel buttons in Czech. ➢ Certain PDFs were not printed correctly, text on PDF was getting printed as blocks. ➢ Improved Barcode scanning. ➢ Improvement in print performance of certain PDF files. ➢ You may see an Access Denied warning when trying to accesses the EWS even prior to entering in a Password. ➢ Under certain circumstances an SNMP GET request might receive a slow response which exceeds all client retries and timeouts. Sometimes the printer would never respond. This fix ensures that these circumstances do not prevent timely SNMP responses. ➢ Intermixing of pages is seen when printing mopy jobs. ➢ Embedded EPrint setting intermittently shows state as "Not Supported" instead of "Enabled/Disabled" via WJA. ➢ Using the Pages per Sheet N-Up printing feature provided with any version of the UPD PCL6 driver will give incorrect printed output. ➢ You may see improvements printing certain fonts. ➢ 49.38.07 error is seen when printing certain jobs with "reverse page order" setting enabled on a device without finisher. ➢ PS Error seen when printing certain documents greater than 40 pages. ➢ Added a Web Service object for the "Security" -> "Web Scan Auto Capture Jobs: Enable Remote User Auto Capture" feature which will allow Web Jet admin to fleet manage this setting with XTP Tickets where reservation less scanning for Network TWAIN is required. ➢ 49.4A.04 is seen when printing certain PDF files containing excessive numbers of XObjects on one or more pages ➢ Error 49.4A.04 is seen when reprinting certain jobs from Corel Draw. ➢ The PCL commands to call barcode fonts does not work when using asterisks ➢ 49.38.07 error is seen when printing certain PDF jobs in duplex. ➢ Color mismatch while printing certain PDF documents and selecting the CMYK profile in driver. ➢ Device stops responding to SNMP requests when we go to Device tab in WJA. ➢ USB volume name is not getting displayed correctly in Korean and other 2 byte languages. ➢ Missing graphics on pages when printing certain PCL5 jobs. ➢ Improvements in small job print performance. ➢ Display brightness value is getting reset to default on a power cycle. Security/Authentication: ➢ Resolved issue where aftermarket authentication agents utilizing the OXPd protocol could inadvertently remove guest permissions to tabs (e.g. the Information tab) on the EWS page. ➢ "This firmware addresses the following security issue:➢ CVE-2016-2183 – 3DES TLS/SSL Birthday Attacks on 64-bit Block Ciphers (SWEET32) Vulnerability." ➢ Re-added web services (removed in FS 3.8) to allow HP Jet Advantage Security Manager to manage the state of the Information tab in the embedded web server. ➢ Resolved redundant authentication prompts when accessing certain types of logs. ➢ This firmware addresses the following security issue: CVE-2017-2750 - Insecure Solution DLL Signature Validation. ➢ Added support for G&D FIPS-201 SIPR smartcards that are provisioned without encipherment certificates. ➢ When logging into the Embedded Web Server using Windows authentication, you may not be able to see all the tabs or options that you have been granted access to. ➢ This firmware addresses the following security issues: CVE-2017-13077: Reinstallation of the pairwise encryption key (PTK-TK) in the 4- way handshake. CVE-2017-13078: Reinstallation of the group key (GTK) in the 4- way handshake. CVE-2017-13079: Reinstallation of the integrity group key (IGTK) in the 4-way handshake. CVE-2017-13080: Reinstallation of the group key (GTK) in the group key handshake. CVE-2017-13081: Reinstallation of the integrity group key (IGTK) in the group key handshake. ➢ This firmware disables the "TFTP Configuration File" setting to prevent unauthorized device resets. Embedded JetDirect: ➢ Fixed "IP Address/Subnet is out of range. Check the field. IP=x.x.x.x Mask=x.x.x.x" error given when an IP address was entered with zero for the host number in the Access Control List. ➢ Buffers expanded to hold large DNS responses (70+ records). Previously only about 7 or 8 records were accepted. ➢ Trying to connect via the FTP may fail with certain applications. ➢ Fixed an issue where Windows Authentication would hang the printer. ➢ Product was generating Certificate Signing Requests with version number other than zero. RFC 2986 requires a version number of zero. ➢ Product was generating Certificate Signing Requests with version number other than zero. RFC 2986 requires a version number of zero. ➢ Printer crashes with 81.09.00 Embedded Jetdirect Error message when user sets Admin password from Telnet. ➢ Under certain circumstances during initial power-on, the DCHP Discover message is sent without a hostname (option 81). This fix ensures that option 81 is always present when applicable. ➢ The password input for "Import Certificate and Private Key" has been expanded beyond 16 characters. ➢ Default name when saving a CSR (Certificate Signing Request) is no longer "certificate.cer". ➢ Under certain circumstances the certificate validity check performed during the IKE portion of IPsec was done with the local printer time and not UTC time
