  • Patent number: 9195919
    Abstract: A method of forming print instructions in a host for rendering within a fixed amount of memory on a printer receives intermediate data comprising regions which are associated with drawing instructions. A first amount of memory available to render the intermediate data is calculated based on a second amount of memory needed by the printer to store the intermediate data. The host determines a subset of the drawing instructions as complex drawing instructions and renders the complex drawing instructions to the printer as simpler drawing instructions. For regions associated with the complex drawing instructions, the host reassociates the regions with the corresponding simpler drawing instructions to form altered intermediate data which can be rendered on the printer within the determined first amount of memory. The print instructions, including the altered intermediate print data, can then be rendered by the printer to pixel data within the fixed amount of memory.
