Hewlett Packard (HP) has released a new firmware for the company's Officejet printers that appears to prevent the use of ink from third-party manufacturers.
The company caused the sallow one year ago when a firmware was released for some of its printers, which prevented the use of ink from non-cassettes HP. 
HP released a software update a month later that restored all functionality and enabled inks third party printers.
The new Hewlett Packard firmware update released on September 13, 2017 seems to be accurate copy of the firmware update that was released a year ago (on the exact same day).
Printers show the following error message after installing the new firmware in the printer:
One or more cartridges appear to be damaged. Remove and replace with new cassette.
Affected printer models include printers: HP OfficeJet 6800 Series, HP OfficeJet Pro 6200 Series, HP OfficeJet Pro X 450 Series, HP OfficeJet Pro 8600 series and many other models.
But as it seems refusal μελανιών που δεν ανήκουν στην εταιρεία από τους εκτυπωτές της HP, οφείλεται σε ένα χαρακτηριστικό που ονομάζεται Dynamic Security.
The HP Support page “HP Inkjet Printers - Dynamic Security Feature Affecting Cartridges Using Non-HP Security Chip”Gives instructions on how to deactivate Dynamic Security and the ban on inks by third parties will stop.
After that, you have two options to avoid future problems:
Exclude automatic update on your Hewlett Packard printer.
or Change printer company
