4. The Auto-Configuration UI control on the Device Settings tab will remain ENABLED
allowing Administrators to manually invoke the Printer Automatic Configuration from
the driver itself.
5. The Status Notification Pop-ups will not display if Printer Automatic Configuration is
disabled. Status Notification Pop-ups require the ability to communicate to the devices
via SNMP.
b. Enabled (Auto Configuration Takes Priority)

Communication protocols
Bidirectional communication between the HP UPD driver and the target device occurs directly (USB
or parallel connection) or over the network:
●
SNMP over the network: UDP ports 160 (general request/response messages).
●
HTTP over the network (Job Capabilities Ticket): a compressed file that can be sent to the
UPD over http that defines specifications for the target device. JCT implementation in UPD v5
only includes media types, paper type and HP Easy Color. Device supporting JCT will also
communicate SNMP information during bidirectional communication, therefore JCT supported
devices may display more capabilities compared to non JCT supported devices.
●
PML over DOT4: DOT4 is based on the IEEE 1284.4 protocol. For direct connect, DOT4 over
USB or DOT4 over LPT is used for most devices. Many composite devices do not support DOT4
and may support an alternate directional mechanism.
● Low end device model (LEDM) over Composite USB: Beginning with UPD v4.7 the UPD can
query low end laser models direct to get device configuration, status and alerts over composite
USB. If the low end device is also networked, UPD printer automatic configuration will use the
network.
Printer Automatic Configuration services
HP UPD installs two services that enable Printer Automatic Configuration to function. In combination
these services allow the HP UPD to retrieve device configuration after installation, using UPDATE
NOW, or via command line using RUNDLL32.
● Net Driver HPZ12: Provides channelized data transfers over the network for scan and fax
●
Pml Driver HPZ12: For USB connected devices that support PML or for network SNMP,
provides the ability to determine what features a device has using printer automatic configuration
and device status.
