Keeping this fairly high-level, there are two basic options:
1. Use the OnBaseVirtualPrintDriver.msi
a. You can deploy the VPD MSI via Active Directory.
- Microsoft lists sets of steps for deploying an MSI via Active Directory here: How to use Group Policy to remotely install software in Windows Server 2003
2. Alternatively, you could also create a batch file to install VPD on each machine.
More information about deployment is available in the Virtual Print Driver MRG.
