I recently posted and then resolved a problem with upgrading the firmware with an OfficeJet Pro X576 with a very early version of firmware. The solution was: calling HP, then receiving an email with a link, user name and password to download earlier firmware versions. Since posting that the link fixed my issue, I've been asked if i could share the link and password. Is that allowed? I would like to help and save someone a phone call but dont want to break forum guidelines.
