If you own an HP OfficeJet Pro 8620, you know it is a workhorse. Released as part of HP’s legendary Pro series, this all-in-one printer has served homes and small offices for years with reliable speed, duplex printing, and massive ink cartridge yields.

While a firmware rollback offers clear benefits, it is important to understand the potential drawbacks before proceeding.
