Abstract: A modular shelving system comprises a first upright, a second upright, first and second rails, and a rail spanner. The first upright includes a first body and a first cleat having a base portion secured in the first body. The second upright includes a second body and a second cleat having a base portion secured in the second body. Each of the first and second rails defines an upper cleat hole and a lower cleat hole. The first cleat of the first upright is slidably received in the upper and lower cleat holes of the first rail, and the second cleat of the second upright is slidably received in the upper and lower cleat holes of the second rail. The rail spanner extends between the first and second rails and includes first and second retaining claws each connected to the rail spanner.

Abstract: Assembly of a structurally sound modular shelving system includes forming an H-shaped base structure, or otherwise-shaped base structure, by releasably hooking a tie beam into a first base piece and a second base piece. A first column member is slid into the first base piece by sliding an insert tab at an end of an elongate body of the first column into a vertical passage through the first base piece. A second column member is similarly slid into a second base piece. A header member is releasably hooked into the first and second columns, the header member extending substantially horizontally between the first and second columns and substantially perpendicularly to the first and second base pieces.

Abstract: The invention is directed to resuming printing on a printer following a print interruption event. An apparatus in accordance with an embodiment of the present invention includes: a scanner configurable to communicate with a printer and a printing application, wherein the scanner is configured to scan a printing at the printer upon receipt of a printing error. A method in accordance with an embodiment of the present invention includes: receiving a printing error when printing a document; scanning the actual printing of the document at a printer; and notifying an application of results of the scanning.

Abstract: A low paper sensor mechanism including first and second support rollers rotatable about a first and second rotational axis to support a paper supply roll, the first and second support rollers and rotational axes configured to translate in a path between a first position and a second position, first and second biasing members biasing the first and second support rollers toward the second position and a detection device, including a light emitting element and a light detecting element, disposed adjacent to the first and second support rollers, wherein the first and second support rollers move from the first position to the second position when a diameter of the paper supply roll is less than or equal to the predetermined distance between the first and second support rollers and the paper supply roll disrupts a line of sight between the light emitting element and the light detecting element.

Abstract: A method for setting color thermal paper parameters including: printing a first color at one or more printing speeds, wherein one or more first color images are produced; selecting the first color image with a desired quality; printing a second color at one or more energy levels at the printing speed corresponding to the selected first color image, wherein one or more second color images are produce; selecting the second color image with the desired quality; and storing a printer parameter corresponding to the selected first and second color images.

Abstract: A plurality of specialized controllers (e.g., 202, 204 & 206), each one adapted to control a particular type of data transfer operation, control the flow of data between a system bus (104) and a local bus (106) on a computer adapter card (102). When the Direct Memory Access (DMA) controller (202) is controlling a DMA operation on the local bus, certain other controllers (204 & 206) can break-in to the current DMA operation, temporarily halting the DMA opertion until the other controller has completed its data transfer operation. To break-in to a DMA operation, handshaking signals between the DMA controller and the local bus interface circuit (212) are temporarily blocked by blocking signals from a break-in logic circuit (210). The break-in circuit includes a four-state state machine to block the handshaking signals at the appropriate times, and to signal the interrupting controller to begin its data transfer operation.
