Hello, I’m Nathan, and I’ll be assisting you today. My livelihood depends on your positive feedback, so your satisfaction is my highest priority.
Sorry to hear you’re having trouble.
Yes, there is a win7 driver for this printer: http://ftp.hp.com/pub/softlib/software11/COL30677/mp-76047-2/PS_AIO_02_USW_Full_Win_WW_130_140.exe
or use: http://bit.ly/24WIiin (same thing, different link, as sometimes this type of file can be blocked, but it is safe to download).
Note however that as this is a very old model it is no longer supported and you would lose functionality if you upgraded further to windows 10.
Do you need more help with this?
