Abstract: An inkjet printer having at least one print head in which an aerodynamic element is placed before (e.g. in a transport direction) a recording medium (e.g. in the form of a sheet or page or plate) to reduce or avoid turbulences that may arise due to the relative motion between print head(s) and recording medium at an edge of the recording medium.

Abstract: Methods and systems are presented for data distribution in which batch evaluations of aggregate performances of taskset-completing participants conditionally trigger eligibility notifications for upcoming on-chain batch data distributions (of cryptoassets, provenance data, or other on-list content, e.g.).

Abstract: Method of printing individual header cards with a limited amount of information, such as a barcode, employing continuous movement of each of the header cards through a gap defined between a backup roll and a thermal printing head, each header card partially wrapping the backup roll only in the immediate vicinity of the printer head.

Abstract: A carrier for holding a conventional envelope in a predetermined position to enable printing near an edge of the envelope with a conventional printer is disclosed. The carrier includes a sheet-like substrate having a leading edge, a trailing edge, a closure flap receiving slot between the leading and trailing edges, and means for holding at least a portion of a bottom edge of the envelope to the substrate. A method according to the present invention includes the steps of providing an envelope, providing a carrier for holding the envelope in a predetermined position, and providing a conventional printer. A closure flap of the envelope is inserted through a closure flap receiving slot in the carrier. Next, a bottom edge of the envelope is held against the carrier. Then, the carrier and the envelope are passed through the conventional printer, which prints on the envelope.

Abstract: A paper holding apparatus suitable for holding undersized paper products in a typewriter mechanism. The paper holder includes two flexible plastic strips mounted on a backing. The strips have opposed recesses in which the undersized paper product may be positioned. The holder is of sufficient size to operate normally in a typewriter mechanism. It may be reusable or disposable depending upon the application.

Abstract: The invention is a document printing aid for microcomputer printers. The invention includes a flexible mask of material, larger than the document to be printed, with an outline of the document on the face of the mask. The printing aid is inserted into a microcomputer printer. The document is placed behind the printing aid and is aligned with the outline. The document, held between the printing aid and roller, is positioned for printing. Apertures in the printing aid allow the printing element to contact the document.

Abstract: The continuous stationery carrier which is adapted to be fed through computer printers, word processing printers, and the like so as to permit the stationery carried therein to be printed upon comprises a plurality of polyethylene backing sheets sequentially joined together along perforated fold lines and equipped with a plurality of feed apertures along the right and left margins thereof. Each backing sheet has a polyethylene cover sheet joined thereto in pocket forming relationship therewith so as to be capable of retaining a piece of stationery. Each cover sheet is provided with at least one aperture therein through which the stationery may be printed upon. The shape and the size of the cover sheets and the apertures therein may be selected to suit a particular application.

Abstract: An index card having a predetermined size has at least two typewriter or printer retaining borders which are joined to the index card on intersecting edges of the typing or printing area of the index card by perforated lines or score lines so that after the index card has been typed, the typewriter or printer retaining borders can be easily detached to result in a standard 3".times.5" card, for example. The typewriter or printer retaining borders retain the typing or printing area in proper position when typing or printing at the "bottom" of the typing or printing area of the index card.

Abstract: An apparatus for standardizing typewriting margins comprising a front sheet having lateral and longitudinal edges which has a window, and a back sheet attached along a seam adjacent three edges to the front sheet which leaves an opening along one edge. A leaf of paper is placed between the front and back sheets along the seam for holding the leaf in place. The window is of a certain given size such that the portion of the leaf showing through the window is the portion to be typed upon. The predetermined margins on the leaf of paper, both lateral and longitudinal, are covered by the front sheet. A scale is disposed adjacent a lateral edge to indicate the number of typewriting spaces remaining before a predetermined margin is reached. Graduations are disposed adjacent both longitudinal edges for indicating the number of lines remaining before a predetermined margin is reached.
