You are searching for HP 1220c drivers and can’t find them on the internet?
The Problem is that HP does not offer drivers because what they say: Windows must provide it. And Windows can’t find any driver. Bad luck!
But here i got a Link for you where you can download it.
It is not like all the other drivers, it automatically adds the drivers for your USB port by using PrintBRM by Microsoft.
Just run the CMD file as Administrator
