HP Recommended
Product: OfficeJet Pro 6978
Operating System: Microsoft Windows 10 (64-bit)

Since the (automatic) firmware upgrade in April to version 1910A, I am not able to use my non-HP cartridges anymore. I have been looking to find the previous firmware version, but can't locate it anywhere. The few links to websites with older HP firmware versions , always generate an Access Denied error.

Who has the working location for the previous firmware version for my printer?

 

Thanks!

Dimitri
