NOTE: The Windows software installer installs the HP Smart Device Agent Base service. The le 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 driveronly web packs downloaded from www.hp.com for the printer and installed through the Add Printer wizard do
not install this service.
