HP UPD - System Administrator's Guide HP UPD 5.6.5

f. Run UPD's Printer Automatic Configuration through the HP UPD driver user interface or the
command line specific to the installed UPD version (see
Command line interface on page 69).
g. Check the device capabilities updated from the default settings.
7. Does the following message, "Windows Security Alert: Spooler Subsystem App" generated during the
installation relate the HP UPD's installed bidirectional communication services over the network?
The HP UPD installation can make calls over the network utilizing different ports and communication
protocols for configuration, device capabilities, and status. For example, ports 160 and 80 might all be
utilized in the Printer Automatic Configuration process when the UPD communicates bidirectional over
the network to the target device. If the ports used by the print spooler are not open, the firewall might
need to be configured.
8. Is there a tool or steps to test SNMP port access required by UPD printer automatic configuration?
The SNMP port utilization by HP UPD will not be active until traffic is being sent or received during the
Update Now process. Full diagnosis involves checking port access at all connection points of the
network between the HP UPD printing client and target device (gateway/routers/switches/server and
host firewalls). Utilities to help troubleshoot connection path access can include Net Print, netstat,
tracert, and pathping to identify network device access. SNMP port utilization by HP UPD will not be
active until traffic is being sent or received during the Update Now process making a network sniffer
one of the best tools for diagnostics during the update process.
9. Why does RGB color from the Color tab only have a NULL option?
The Color Themes from the Color tab in the HP UPD properties is device dependent. The HP UPD
configures the settings based on the model name. If the Device Type is set to Color in the Device
Settings tab (DCU or manually) and if there is no bidi communication with the color product, then the HP
UPD displays NULL. When using the PCL 6 driver, the HP EasyColor option is not available either.
