INTRODUCTION ******************** The HP SNMP Proxy Agent is software that can be loaded to a desktop client pc to allow HP Web JetAdmin 8.1 to discover and manage locally connected (USB, LPT) printers. The HP SNMP Proxy Agent functions by exposing printer MIB OIDs to the client’s Microsoft SNMP service. The HP PC Printer Discovery plug-in will no lomger be required to discover direct connected printers on machines running the HP SNMP Proxy. A simple network printer discovery in HP Web Jetadmin can now discover locally attached printers. Additional printer information can be gathered through the proxy such as remaining toner levels, page counts, status, etc. ***************** II. What's New ***************** Version 1.1.2.52 of the HP SNMP Proxy Agent for HP Web Jetadmin 8.1.3570 is the first release and includes the following functionality: 1) Web JetAdmin will query the standard printer and enterprise PML OIDs in the supported printers. In most cases, the printer model name, engine page count, toner levels, serial number, etc. are available. Many recent enterprise devices support additional objects, while some of the lower end personal printers may not support many objects at all. 2) While visible in the product, configuration and alerts are not supported for this first release. Only reading of information from PC connected printers is supporting, not writing. 3) Traps (events) from PC connected printers are not supported to detect device status and/or process alerts. Web JetAdmin 8.1 will only detect changes in a device by polling or manually refreshing the device. 4) Supported discovery methods of PC Connected printers include IP Broadcast, Specified Address, IP Range and Quick Device Find. 5) If a proxied windows host fails to respond to HP enterprise printer OIDs during discovery (because the printer is powered off/disconnected, or the printer driver’s I/O stack lacks a supported bi-di interface), Web JetAdmin classifies the host as a “windows workstation” and does not place it in the All Devices list. Thus, if a supported PC connected printer is newly attached to a proxied workstation and a supported driver is installed, the printer will not be visible in the All Devices list until another discovery has completed. 6) Only a single supported printer attached to each client computer will be discovered. The agent instruments the current user’s default printer if supported, else it instruments the first supported printer it finds. Multiple printers connected to a single client machine will be supported in a future release. 7) Printers must have a DOT4 bi-di capable driver installed in order to be discovered. ************************** III. SYSTEM REQUIREMENTS ************************** Listed below are the minimum (and recommended) system requirements in order to install the HP SNMP Proxy Agent: - Intel® Pentium® or Celeron™ processor (Pentium II or higher recommended) - 64 MB RAM (128 MB RAM or higher recommended) - 10 MB available hard disk space HP SNMP Proxy Agent is supported only on the following Microsoft Windows operating systems: - Windows 2000 (SP 4) - Windows XP (SP 2) - Windows Server 2003 Enterprise Edition Windows SNMP service must be installed and configured to allow queries from the WJA server. The community name should be set to public for read access (Refer to the Installation section of the User Manual) Firewall settings should be appropriately modified to allow WJA to query the proxy agent (i.e. UDP port 161 should be open for SNMP queries). ****************** IV. INSTALLATION ****************** Two modes of installation are available: 1) Standalone installation: This will be the standard (non-silent) installation which takes input from the user in the form of responses to dialog boxes. Administrators can install the package using either the EXE package or the MSI package as such: - Installation through MSI package: Administrator double clicks the HP SNMP Proxy.msi file or runs the Msiexec /i “HP SNMP Proxy.msi” command. - Installation through EXE package: Administrator double clicks the hp_snmp_proxy.exe file or runs the hp_snmp_proxy.exe /i command. Thereafter the user will be guided by the installer through a series of dialogs. 2) Silent Mode Installation/Network Installation: The silent mode of installation is provided for “push” based installations. Administrators can initiate a silent installation (without UI) with the following commands. - Installation through MSI package: Msiexec /i “HP SNMP Proxy.msi” /qn - Installation through EXE package: hp_snmp_proxy.exe /s /i *********************** V. Supported Printers *********************** The HP SNMP Proxy Agent supports a wide variety of HP printers as long as they are installed using a DOT4 bi-directional capable driver. A complete list of tested printers can be found in the whitepaper titled "Discovering PC Connected Printers in HP Web Jetadmin". ************** VI. Q & A ************** 1) Question: Why doesn't Web Jetadmin discover my locally attached printer? Answer: Several reasons could account for the printer not being discovered. The following troubleshooting steps may help: a) Verify basic network connectivity with ping at the Web JetAdmin server’s host to the client host. b) At the Web JetAdmin server, use a 3rd party tool such as net-snmp’s snmpget to verify basic SNMP service on the Windows client. E.g: snmpget –v 2c –c public clienthostname 1.3.6.1.2.1.1.1.0 c) At the Web JetAdmin server, use a 3rd party tool such as net-snmp’s snmpget to verify the successful installation of the HP SNMP Proxy agent. E.g: snmpget –v 2c –c public clienthostname 1.3.6.1.4.1.11.2.4.3.13.1.0 If the agent, printer driver and printer are all functioning, the agent responds with the INTEGER 1. The agent responds with error NO SUCH NAME if installed/configured successfully but now unable to communicate with the printer. d) You can identify a client’s version and supported printer by checking the registry entries under “HKLM\SOFTWARE\Hewlett-Packard\HP SNMP Proxy” identifying the supported printer. 2) Question: Once I run a network printer discovery and the locally attached printers are discovered, how do I know which ones are PC connected printers? Answer: Discovered PC connected printers will appear in the All Devices list with the rest of the networked printers. However, the PC connected printers will be distinguished in the Port column as "PC Port". This column could be sorted to quickly create a group of locally attached printers. Autogrouping could be enabled with a filter on Port equaling "PC Port" to automatically create groups containing just PC connected printers. 3) Question: Can I generate reports using Report Generation Plug-in on my locally attached printers? Answer: Yes, reports should be possible on PC connected printers. Of course, the data that can be collected will differ from device to device. 4) Question: Can I use any version of HP Web Jetadmin to discover PC connected printers? Answer: It depends upon whether the HP SNMP Proxy Agent is installed on clients. For cases where it is, only HP Web Jetadmin 8.1.3570 is supported to properly query those client machines for the printer information. For cases where the HP SNMP Proxy Agent is not in use, the PC Printer Discovery plug-in can be used in any supported version of HP Web Jetadmin to just discover the locally attached printers using WMI. No additional information other than device model can be collected using PC Printer Discovery plug-in. ***************************************************************** VII.
