In one example of the disclosure, a system for print fluid recirculation includes a supply manifold, a recirculation manifold, a printbar, and a recirculation pathway. The printbar includes a plurality of printheads that are in fluid communication with the supply manifold, and the recirculation manifold. The recirculation pathway is in fluid connection with the supply manifold and the recirculation manifold, and is to enable recirculation of print fluid at a controlled flow through the plurality of printheads.

According to examples, systems and methods for transferring and mixing ink utilizing a tank with a mixing area formed by a funnel portion are described. The mixing area is for mixing new ink and resident ink. In some examples, a new ink supply inlet tube deposits the new ink into the tank from a connected ink supply container. In some examples, a resident ink supply inlet tube deposits the resident ink into the tank from a connected printing device. In some examples, an outlet port situated at tank bottom sends the mixed ink to the printing device.

A first roller has a first roller center line; a second roller has a second roller center line. Fluid-ejection mechanisms eject fluid onto the media as the media is rolled past the rollers, and include first mechanisms and second mechanisms. The first mechanisms include first and second printheads, at least substantially equally between which a first positioning line is defined. The second mechanisms include third and fourth printheads, at least substantially equally between which a second positioning line is defined. The fluid-ejection mechanisms are disposed opposite to the roller and are positioned such that the first and second positioning lines are located between the first and second roller center lines, the first and the third printheads are not completely located between the first and the second roller center lines, and the second and the fourth printheads are completely located between the first and the second roller center lines.

A embodiment of a stand includes a base, a support, and a biasing member. The biasing member provides a biasing force to urge the support to a first position relative to the base from a second position relative to the base. When in the second position the support is allowed to rotate on a pivot, and when in the first position the support is prevented from rotating on the pivot.

A device stabilizer, according to an embodiment, includes a latch, an elevation lock, and an actuator. The latch, when engaged, holds an outrigger in a closed position. The elevation lock, when engaged, holds a device at a selected elevation. The actuator includes a button that when pressed at least indirectly disengages the elevation lock and the latch.

An adjustable support for a multimedia display device includes a base, a ring rotatably coupled with the base, and a foot mated with the ring and coupled with the base. The ring includes a plurality of ramp surfaces, and the foot includes a plurality of engaging surfaces. The plurality of ramp surfaces are separate from each other and distributed at substantially equal intervals along a common circumference, and each of the engaging surfaces interacts with a respective one of the ramp surfaces, wherein rotation of the ring relative to the base causes each of the engaging surfaces to slide along the respective one of the ramp surfaces to vary a distance the foot extends from the base.

An adjustable support for a multimedia display device includes a base and a foot rotatably coupled with the base. The base includes a plurality of ramp surfaces, and the foot includes a plurality of engaging surfaces. The plurality of ramp surfaces are separate from each other and distributed at substantially equal intervals along a common circumference, and each of the engaging surfaces interacts with a respective one of the ramp surfaces, wherein rotation of the foot relative to the base causes each of the engaging surfaces to slide along the respective one of the ramp surfaces to vary a distance the foot extends from the base.

An input device, which is capable of changing the appearance of a display, includes a body made up of a cover and a base, a cable receiver, and a cable coupled to the cable receiver. The input device has a first mode with a first portion of the cable having a first length external to the input device and a second portion of the cable wrapped around the cable receiver. The input device also has a second mode with the first portion of the cable having a second length external to the input device less than the first length.

Input device with cable storage

An image projection system is provided that includes a portable projector, where the projector includes a light engine, and a projector housing having a closed configuration and an open configuration, where in the closed configuration the projector housing at least partially encloses the light engine, and in the open configuration the projector housing supports the light engine.

Portable projector system

A pointing device, which is capable of changing the appearance of a display, includes a housing made up of a cover and a base, a single spool cable receiver rotatably mounted to the housing, and a cable having a first end and a second end with the second end mounted to the cable receiver. The pointing device has a first mode with a first portion of the cable having a first length external to the pointing device and a second portion of the cable wound around the cable receiver. The pointing device also has a second mode with the first portion of the cable having a second length external to the pointing device less than the first length.

A multifunction peripheral server discovery method with reduced network traffic is disclosed. Peripheral servers on a network advertise their basic function, such as print, and clients seeking peripherals with an additional function, such as scan, retrieve ID strings of peripherals having the basic function to determine if the additional function is available. The method also permits a user of a client on the network to enter addresses of peripherals not discovered when the client searches for peripherals having the additional function. The method also permits selection of a network protocol to be used by the client. An additional preferred step in the method is a determination of whether discovered peripherals having the additional function are compatible with a software application run by the client.

Network peripheral server discovery method

A configurable printer driver, resident on a host (source) computer is enabled to respond to a print job request by manipulating a source bitmap prior to its transmission to a destination printer. The printer driver includes plural, substantially independent, bitmap manipulation procedures which may be linked to provide an image processing pipeline. The method of the invention initially determines which bitmap manipulations should be performed on the source computer, to minimize the quantity of bitmap data to be dispatched to the destination printer or to maximize processing efficiency of the print job request. Based upon the aforesaid determination, a bitmap processor pipeline is assembled from stored bitmap manipulation procedures to perform manipulations of the source bitmap in the source computer. The bitmap manipulations are then performed, using the assembled bitmap processor pipeline. The resulting processed raster bitmap is then transferred to the destination printer.
