  • Patent number: 11323588
    Abstract: Examples techniques to determine print material subscription plans for image rendering devices are described. In an example, data indicative of print material consumption by an image rendering device for a period of time is received at a server. Based on the received data, a print material subscription plan is determined for the image rendering device. Signals to enable provision of a notification corresponding to first print material subscription plan are transmitted to the image rendering device.
    Type: Grant
    Filed: June 29, 2018
    Date of Patent: May 3, 2022
    Assignee: Hewlett-Packard Development Company, L.P.

  • Patent number: 9914297
    Abstract: A fluid ejection device is described. In an example, a device includes a substrate having a chamber formed thereon to contain a fluid. A metal layer includes a resistor under the chamber having a surface thermally coupled to the chamber. At least one layer is deposited on the metal layer. A polysilicon layer is under the metal layer comprising a polysilicon structure under the resistor to change topography of the resistor such that the surface is uneven.
