When creating an image for Windows 7 one would like to install drivers for printers and configure them for the users. However, after sysprepping the machine, the printers and configurations are gone.
To resolve this issue, add the following component to the <settings pass = "generalize"> section of your unattend.xml file.
<component name="Microsoft-Windows-PnpSysprep" processorArchitecture="x86" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS">
<DoNotCleanUpNonPresentDevices>true</DoNotCleanUpNonPresentDevices>
<PersistAllDeviceInstalls>true</PersistAllDeviceInstalls>
</component>
