A product key is required to proceed and use Windows 95. In one form, product activation refers to a method invented by Ric Richardson and patented (U.S. patent 5,490,216) by Uniloc where a software application hashes hardware serial numbers and an ID number specific to the product's license (a product key) to
This allowed adding printers via a user interface similar to the one Microsoft Windows uses, where a new printer could be added using an add new printer wizard, along with changing default printer properties in a window containing a list of installed printers.
Beyond driver configuration, HP UPD also employs managed printer lists (MPLs) and managed print policies (MPP) to control access to devices and capabilities. These technologies are used with HP UPD in dynamic mode. If MPLs are used, then searching for devices is unnecessary. Users are presented with a predefined list of devices from which to ...
