Abstract: Embodiments generally relate to link state change detection and notification within a server with embedded or directly integrated network switch. In a server configuration in which there is no longer a distinct separation between a network switch and a network interface card (NIC), the server can no longer immediately detect a change in the link state of any of the switch's ports. This can lead to connection failure. A Link State Policy Table is thus implemented within the embedded or integrated switch, capable of changing the NIC link state according to one or more pre-defined or user-defined policy settings. The server is then notified of the change in the NIC link state, and can release an old IP address or request a new IP address accordingly.

Abstract: A compound inkjet print head printer has a compound print head module. The compound print head module includes at least two inkjet print heads for providing ink droplets of one color but with different sizes. Since the compound inkjet print head module provides different sizes of ink droplets in a swath, the number of print swaths can be decreased. The compound inkjet print head printer increases a printing speed with high photo quality.

Abstract: A method creates printing data applied to a printer that is capable of generating different sizes of ink drops. Firstly, a halftoning threshold table is created based on all possible combinations that are determined based on the quantity of the printheads and the sizes of ink drops quantity provided by each printhead. When the image data to be printed is received, each pixel of an image will correspond to one combination based on the halftoning threshold table. The corresponding combination is deemed as a halftoning encoded data and represented by several bits. These bits can be separated into plural groups, where the bits contained in each group are for driving a specific printhead. That is to say, each printhead has its own driving data so that the printing process will have superior efficiency.

Abstract: An image processing mechanism combines the halftone method and image enhancement technique for processing halftone and improving image performance. The mechanism includes an image input module, an image enhancement module and a halftone module. The image input module sends the original image data to the image enhancement module to enhance the image by filtering. The halftone module processes the enhanced image data by the algorithm of error diffusion. It combines two different processes into one mechanism to simplify the hardware architecture and to decrease the usage of memory.
