Printer Automatic Configuration
Automatic Configuration enables the HP UPD driver user interface to reflect the supported capabilities of the target
print device. Automatic configuration occurs through bidirectional communication between the product and a HP UPD.
This communication can occur over the network or a USB direct connection. When the user installs the driver, the
default printer model options will be base model. Successful implementation requires the HP UPD installed
bidirectional services (Net Driver HPZ12 and Pml Driver HPZ12) are loaded, the correct port settings are set, and the
target product is available for direct connect to the host or over the network. If the communication is successful, the
printer options will be updated in the driver user interface.
This process of the HP UPD sending request and accepting responses directly between the driver and the device is
referred as 'bidi' for bidirectional communication. The HP UPD user interface options will change to enable features of
the target device based on the result of the response query (installable trays, Duplexer, Accessory Output Bin, HP
EasyColor, etc.). If the communication is unsuccessful, the driver will still have base model functionality presented in
the HP UPD user interface. Extended options will not be displayed or available for use during File-Print.
The benefit of Printer Auto-Configuration is enabling the driver to query the printer and recognize the product’s
capabilities with a level of automation and accuracy.
Printer Automatic Configuration can only be launched in the following methods:
HP UPD driver installation (automatic update to all queues utilizing the HP UPD)
Dynamic mode—Each time Print is selected from the HP UPD client.
Update Now GUI—Traditional mode installations can manually launch through the HP UPD driver User Interface:
Printer Properties, Device Settings tab, Installable Options, Automatic Configuration, Update Now.
UPDATE COMMAND LINE—Traditional mode installations can execute a command line using Microsoft's
Rundll32.dll allowing change updates to occur through scripting. (see Command line interface).
Automatic Printer Configuration status
Dynamic mode—Invoke Printer Automatic Configuration each time the HP UPD user interface is invoked (print
properties for FILE-PRINT from the application).
Traditional mode—Printer Automatic Configuration Status can be determined by checking the About tab of the HP
UPD available through the HP UPD Printer Properties.
