Method 6: Create a driver instance with plug and play
The HP UPD can be installed for use with plug and play products as either a software first or a hardware first
installation.
●
Software first (unattended) installation – recommended
●
Hardware first installation
Software first (unattended) installation – recommended
In a software first installation, the HP UPD is prestaged on the PC, and will be found and used by the
operating system when the new product is connected. This method does not require any interaction by the
current user, and does not require the user to have administrator privileges.
NOTE: Starting with UPD 5.6.5, new options in install.exe for Windows Vista and later Windows operating
systems add the ability to select USB mode for USB Plug and Play with options to remove all versions of
HP Universal Printing Driver from Windows driver store, or to add the HP Universal Printing Driver to Windows
driver store.
These settings only impact the Windows driver store. No HP UPD printer is installed, no printer driver is
removed and no existing print queues are impacted. Only the HP UPD is only added to the driver store. No
non-HP UPD drivers are impacted.
On Microsoft Windows Vista and later Windows versions, you should use the pnputil driver package utility
to prestage the required drivers before you connect the printer using the USB cable. As some printers require
an LEDM driver and a printer driver, HP recommends prestaging all HP UPD delivered *.inf files with
pnputil, using the command: pnputil –a *.inf. For more information, see
USB connectivity
on page 163.
Pre-configure and install the HP UPD for use with software first installation
NOTE: Preconfiguring and installing the HP UPD works on windows XP for all printers. For Vista and later
windows versions, this works for DOT4 devices, but not for LEDM devices. LEDM devices require the usage of
pnputil.
To pre-configure the HP UPD for a Software first, plug and play installation, use the HP Driver Distribution
Utility (HP DDU), and select the Preload the Driver option. This method creates a package with a
setup.exe utility that is easy to deploy interactively or via scripting. See
Pre-configure the HP UPD default
settings using HP Driver Deployment Utility on page 21 for more information.
Driver selection when multiple drivers are pre-loaded
It is possible that multiple versions of the HP UPD might be prestaged at the time of initiating a Plug-and-
play event. When the operating system detects multiple compatible drivers, it uses the following criteria for
selecting the driver to use:
1. A WHQL certified driver has priority over all other drivers. If all available drivers are WHQL certified, the
operating system considers the next criteria.
2. Microsoft Vista and later operating systems evaluate the driver based on available features. The driver
with the most features is selected. If all drivers are deemed equal the operating system considers the
next criteria.
3. Finally, the operating system selects the driver with the most current date.
