PPA Printer Firmware Design
نویسنده
چکیده
A significant factor in Hewlett-Packard’s new Printing Performance Architecture (see Article 1) is the reduction of the processing power embedded in the printer. Using the host PC for all image formatting leaves only motor, print cartridge, I/O, user interface, command, and status functions to be controlled by the firmware. This results in significant cost savings by reducing processor needs and by reducing ROM and RAM requirements. The goal, which was achieved, was to reduce the ROM requirements to 64K bytes.

When Firmware Modifications Attack: A Case Study of Embedded Exploitation
The ability to update firmware is a feature that is found in nearly all modern embedded systems. We demonstrate how this feature can be exploited to allow attackers to inject malicious firmware modifications into vulnerable embedded devices. We discuss techniques for exploiting such vulnerable functionality and the implementation of a proof of concept printer malware capable of network reconnai...
متن کاملImplications of Malicious 3D Printer Firmware
The utilization of 3D printing technology within the manufacturing process creates an environment that is potentially conducive to malicious activity. Previous research in 3D printing focused on attack vector identification and intellectual property protection. This research develops and implements malicious code using Printrbot’s branch of the open source Marlin 3D printer firmware. Implementa...

متن کاملA Large-Scale Fault-Tolerant Distributed Software-Build Process
A large software system can be compiled and linked more quickly if its build process is distributed across a network of multiple computers. However, large networks are more likely to contain a computer that causes a build to fail. If such a computer can be identified, it can be excluded from participation. Otherwise, if the failed command can be detected, it can be retried on a different comput...
