the network. If the communication is successful, the printer options will be updated in the driver user
interface. This process of the UPD sending request and accepting responses directly between the
driver the device is referred as 'bidi' for bidirectional communication. The UPD driver 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 Easy Color, etc). If the communication is
unsuccessful, the driver will still have base model functionality presented in the UPD driver user
interface and 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
device’s capabilities with a level of automation and accuracy.
Printer Automatic Configuration can only be launched in the following methods.
1. UPD driver installation (automatic update to all queues utilizing the UPD driver)
2. Dynamic mode- each time PRINT is selected from the UPD client.
3. Update Now GUI: Traditional mode installations can manually launch through the UPD driver
User Interface: Printer Properties-Device Settings tab-Installable Options-Automatic
Configuration-Update Now.
4. 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 on page 68.)
Automatic Printer Configuration status
Dynamic mode: invoke Printer Automatic Configuration each time the HP UPD user interface is
invoked (ie- 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.
