note:
The Windows software installer installs the HP Smart Device Agent Base service. The file size is less than 100 kb. Its only function is to check for printers connected via USB hourly. No data is collected. If a USB printer is found, it then tries to locate a JetAdvantage Management Connector (JAMc) instance on the network. If a JAMc is found, the HP Smart Device Agent Base is securely upgraded to a full Smart Device Agent from JAMc, which will then allow printed pages to be accounted for in a Managed Print Services (MPS) account. The driver-only web packs downloaded from www.hp.com for the printer and installed through the Add Printer wizard do not install this service.

To uninstall the service, open the Control Panel, select Programs or Programs and Features, and then select Add/Remove Programs or Uninstall a Program to remove the service. The file name is HPSmartDeviceAgentBase.
