HP MFP Digital Sending Software Version 4.91 - Differences from DSS Version 4.x

Introduction
DSS 4.91 is designed to be backward compatible with DSS 4.x.
  note:
DSS 4.x is meant to include all versions from 4.0 through 4.20
However, there are many new features that have been added, and some old functionality that has been replaced or removed. In order to support FutureSmart devices (e.g. Color LaserJet CM4540) DSS 4.91 was based on the latest Microsoft .Net platform, and has very little programming code in common with DSS 4.x. This white paper details the primary differences in functionality and operation between 4.91 and 4.x.
Important Changes in DSS 4.91
Device status not retrieved when Configuration Utility opens
The status icon will be displayed for all devices on the Device Configuration tab when the DSS 4.91 Configuration Utility opens. This icon means that the status has not been determined for the device. When the legacy DSS 4.x CU opened, it connected with each device to determine its status. However, this automatic operation often required significant time, and with 4.91 the administrator can refresh device status as needed. Refreshing the device status is not required prior to selecting Configure Device…
There are several ways to refresh the device status for a single device or a group of devices.
Single device
Right-click on a device, and select Get Status.
Multiple devices
Click on a device and then use Ctrl-click or Shift-click to select multiple devices.
Or, click on a device, then press Ctrl-A to select all devices in the group.
Then, right-click on a device, and select Get Status.
Device feature icons
The Device Configuration tab has new status icons for features configured on the device.
The feature is configured and does not require authentication.
The feature is configured and requires authentication.
The feature is not configured.
This pale icon indicates that the feature is configured, but the device status has not been retrieved.
Visual aids
The Configuration Utility introduces new methods to indicate when values are required, invalid or not yet applied to the DSS service. There are five primary methods that the CU employs to help the administrator recognize these conditions.
  1. An asterisk (“*”) is displayed on tabs containing values which have not been applied.
  2. An exclamation point (“!”) is displayed on tabs that are missing a required value.
  3. An Information Pane is displayed at the top of the window whenever there are required or invalid values.
  4. A blue highlight is drawn around specific values that are required or invalid.
  5. The Apply button is disabled until all required values are entered and contain valid data.

Backup and Restore
There are buttons on the General tab for Backup and Restore. These buttons only impact the DSS service configuration data and the managed device list.
Instance names
  • DSS service name: HP Digital Sending Software
  • DSS service process: HP.Dss.App.WinService.exe (in Task Manager)
  • Configuration Utility: HP.Dss.App.ConfigurationUtility.View.exe
  • SQL Server service name: SQL Server (HPDSS)
  • IRIS OCR process: dpe_ocr123.exe
New in DSS 4.91
  1. Support for Windows Vista / 7 / 2008
    The following Windows OS versions are supported
    • XP Professional, SP3
    • Server 2003, SP2
    • Vista Business and Vista Enterprise
    • Windows 7 Professional and Windows 7 Enterprise
    • Server 2008 and Server 2008 R2
    These platforms are supported for both 32 and 64 bit where applicable.
    A server reboot is required after installation on Windows Vista, 7 and 2008.
  2. Support for FutureSmart devices
    • Color LaserJet CM4540 MFP
    • ScanJet 7000n Enterprise (requires a firmware upgrade to xxxx)
  3. Configuration Utility improvements
    There are many changes and improvements to the look and feel of the Configuration Utility.
    • Windows are resizable, and will restore their previous size and position between uses
    • The Administrator will be warned if they attempt to exit the CU without applying their changes
    • Ability to create device groups and sub-groups
    • Drag and drop when creating device groups
    • Integrated Address Book Manager and Remote Configuration Utility install
  4. IRIS OCR Engine 12.3.4 with parallel processing
    OCR jobs will be launched in parallel by DSS 4.91. Previously OCR jobs could block other jobs until an individual OCR process completed. Multiple OCR jobs can also be launched at the same time. This will greatly reduce the processing time on servers with multiple processors or cores.
  5. Secure e-mail channel (SMTP over SSL)
    Email packets travelling from the DSS server to an SMTP server may be configured to use a secure channel. This does not encrypt the actual email message, but instead uses a network protocol that encrypts the packets using SSL/TLS. This feature is configured on the E-mail tab using the Add… or Edit… buttons for an outgoing SMTP gateway server.
  6. Device Configuration Templates
    Templates can be created for device configuration settings. These templates are then available to apply to a group of devices, or used as the default settings when adding a new device. Templates must be created before they can be applied to a device. It is not possible to create a template from a configured device.
    For example, assume that all devices in a particular group always need the same Send to Folder settings. You can create a template that only impacts Send to Folder settings. Then whenever a new device is added you can apply the template that only affects Send to Folder.

  7. PDF/A and High Compression PDF for Send to Email and Send to Folder
    DSS 4.91 brings FutureSmart functionality for PDF files to legacy devices. Devices prior to FutureSmart do not have file options for PDF High Compression or PDF/A formats. However, these features can be enabled by editing configuration settings in an XML document. A more complete explanation can be found on TechWeb in the white paper, DSS 4.91 XML Documents.
  8. Log collection utility
    There is a new log collection utility that is installed with DSS 4.91 which will gather all necessary logs and system information. This data is then stored in a ZIP file which can be examined by the customer and sent to HP Technical Support.
    Launch [Install Path]\Scripts\CollectDssLogs\CollectDssLogs.exe
    A .zip file will be created in the CollectDssLogs folder. This file contains information that is very useful to diagnose customer problems. For example, the SystemTraceDss.Log files provide step-by-step execution detail.
  9. Support for an external SQL Server database
    DSS can be configured to connect to a Microsoft SQL Server database on another server, and the local instance of SQL Server Express 2005 can be uninstalled. A more complete explanation can be found on TechWeb in the white paper, DSS 4.91 Configure External Database.
  10. Support for up to 1,000 devices per DSS server
    The DSS service will support 1,000 devices per server. This depends on server configuration, and also on the scan job type and volume. For example, a high volume of OCR jobs will put a greater load on the server. However, in most environments the 1,000 device limit should be attainable.
  11. Scripted configuration backup
    Using the new Backup and Restore buttons in DSS 4.91 is the most convenient way to backup your DSS configuration. However, if you need to perform automated backup and restore of the configuration without user intervention, you can use the following steps.
    Backup
    1. Close the DSS Configuration Utility.
    2. Stop the HP Digital Sending Software service.
    3. Stop the SQL Server (HPDSS) service.
    4. Backup the configuration files

      2. [Install Path]\Hewlett-Packard\HP Digital Sending Software 4.91\Filesystems\CustomerData\Dss
      3. [Install Path]\Microsoft SQL Server\MSSQL.1\MSSQL\Data\Program Files_Hewlett-Packard_*
    5. Start the SQL Server (HPDSS) service.
    6. Start the HP Digital Sending Software service.
    Restore
    1. Close the DSS Configuration Utility.
    2. Stop the HP Digital Sending Software service.
    3. Stop the SQL Server (HPDSS) service.
    4. Restore the configuration files.

      3. [Install Path]\Microsoft SQL Server\MSSQL.1\MSSQL\Data\Program Files_Hewlett-Packard_*
    5. Start the SQL Server (HPDSS) service.
    6. Start the HP Digital Sending Software service.
      note:
    The backup and restore must be on the same machine.
