Example implementations relate to updating firmware. For example, a system according to the present disclosure may include a printing device and a computing device. The printing device may be on a network. The printing device may detect an intrusion against the printing device. The computing device may be on the network. The computing device may receive a broadcast reporting the intrusion directly from the printing device. The computing device may request, responsive to receiving the broadcast, an updated portion of a firmware code image for the computing device.

Updating firmware

Example implementations relate to code package variants. For example, a system according to the present disclosure, may include a client server, a development environment, a digital signing environment, and a central server. The development environment may generate a plurality of variants of a first portion of a code package. The digital signing environment may create a distinct digital signature for each variant of the plurality of variants of the first portion of the code package with a same second portion of the code package. The central server may transmit to the client server a complete code package comprising a variant of the plurality of variants of the first portion of the code package along with the second portion of the code package and a corresponding digital signature. The central server may transmit to the client server an incomplete code package comprising a remainder of the plurality of variants of the first portion of the code package, without the second portion of the code package, and digital signatures of each of the remainder of the plurality of variants.

Code package variants

According to one aspect, a printer checks whether a customized control panel definition is available for the printer. If a customized control panel definition is available for the printer, then the customized control panel definition is retrieved, otherwise a default control panel definition is retrieved. A control panel as defined by the retrieved control panel definition is displayed. According to another aspect, a request to customize control panel of a printer is received. Control panel customization options are displayed, one or more control panel customization selections are received, and a control panel definition for the printer that incorporates the control panel customization selections is saved.
