OfficejetPro86xx-Downgrade
HP intentionally sabotaged their Officejet86xx series of printers (and quite a few others) to reject remanufactured cartridges on 9/13/16. While their intention is to stem illegal production of cloned and patent-infringing ink cartridges, the un-announced nature of this effort has cost many people a large sum of money and even their jobs. This script is designed to upload the timebomb-less firmware until remanufacturing/filling companies can provide updated cartridges. I want to recommend updating firmware back to the latest version once cartridge refillers have a chance to update their chips/software, but due to the lack of warning and the dishonest nature of HP's tactics, I'd disable all updates until further notice. (That's just my opinion.)
Requirements
- HP Officejet 86xx printer connected to local network.
- Netcat (included in most linux distributions)
- HP firmware to "downgrade" with saved in the same directory as this script.
Note: I can not provide the firmware, but I will list the version needed for each printer.
Usage
The script can be executed from any linux system running bash as follows:
./fix.sh 192.168.1.44Change 192.168.1.44 to whatever IP your printer has on the network.
TODO
- Support for Windows and OSX
- Implement OS detection
- Implement firmware selection
- Code cleanup
- Improve future support for more printers
