I was trying to install a driver for an old HP printer and was confused to find two seperate folders: one name "hp" and the other "hewlett packard." Each contained a different set of printer drivers, but both set of drivers are from the same manufacturer. I assumed "hp" and "hewlett packard" are the same company. What could be the reason for this?
Because the people who packaged the driver changed the name field over time. There are quite a few more than that. I often find 4 different spellings of Manufacturers in the driver store. You might get a different name from Microsoft, the OEM, or a repacker like the motherboard OEM.
It's just a text field in the ".INF" file. You could change it. Add a few more.
