I have a problem with identifying printers

Quote:

A hardware ID is a vendor-defined identification string that Windows uses to match a device to an INF file. In most cases, a device has more than one hardware ID associated with it. Typically, a list of hardware IDs is sorted from most to least suitable for a device.

A "Hardware Id" (or "instance" id) is not same as a Serial Number.
