Abstract: When a user sets, from a user interface window using a bookbinding application, instructions of dividing a document into a plurality of parts and stapling each part of the document, a printer driver generates one job in which the staple attribute of a binder corresponding to each part is set to “ON” or “OFF”, and issues the job for a printer. With this operation, the user can perform staple designation to an arbitrary part of the document, and can realize a plurality of staple processes in one print job.

Abstract: A roller for a printer includes an outer tube and at least one inner tube. The inner tube is position within the outer tube. The outer tube extends in an axial direction from a first to a second end and the inner tube extends substantially parallel to the outer tube, defining an inter tubular space between the outer and the inner tube and an intra tubular space within the inner tube. The roller also includes a blocking element dividing the inter tubular space and the intra tubular space into a first part extending substantially from the first end to the blocking element and a second part extending substantially from the blocking element to the second end. A first and a second duct connects the first and second part of the inter tubular space with the second and first part, respectively, of the intra tubular space via the blocking element.

Abstract: A piezoelectric/electrostrictive device comprising, on a ceramic-made substrate, at least one piezoelectric/electrostrictive layer made of a piezoelectric/electrostrictive ceramic composition and at least one pair of electrodes electrically connected to the piezoelectric/electrostrictive layer, characterized in that the piezoelectric/electrostrictive layer is made of a piezoelectric/electrostrictive ceramic composition containing a PbMg1/3Nb2/3O3—PbZrO3—PbTiO3 system composition wherein part of Pb is substituted with at least one kind selected from Sr and La, as a major component and Ce in an amount of 0.01 to 0.50% by mass in terms of CeO2 and that the piezoelectric/electrostrictive layer is solidly attached to the substrate directly or via part of the electrodes.

Abstract: In a head drive circuit for an impact dot printer which performs printing by driving a print wire, a DC power source supplies a power source voltage. A switching element is on/off controlled to apply the power source voltage to a head coil for a predetermined time period. A voltage regulator converts an input voltage having a value higher than the power source voltage into an output voltage having a value as substantially same as the power source voltage. A voltage introducer inputs an inductive voltage, generated in the head coil when the switching element is turned off, into the voltage regulator as the input voltage. A voltage returner feeds back the output voltage of the voltage regulator to the DC power source.

Abstract: A head for a printer and an image processing system is provided in which light emitted from light emitting elements formed on a substrate of the head does not leak from pinholes of a non-corresponding light emitting elements and does not interfere with light emitted by other light emitting elements, so that satisfactory printing can be carried out. An aperture has on opposite ends sandwiching portions and covers a substrate to sandwich a carriage. Concave portions are formed correspondence with light emitting elements. Pinholes are provided in a front wall and an insulating black coat is formed on the surfaces of the concave portions to prevent a short circuit. Light from the light emitting elements which does not pass through the pinholes is absorbed by the surfaces of the concave portions.

Abstract: A single pass printer, having a printing width (PW) is provided or printing a toner image on a substrate, the substrate having a width (WS) and a length (LS), wherein, i) a number n, equal to or larger than 2, of printing engines, each containing a toner transferring element with a longitudinal axis (width (WPE)) smaller than the printing width (PW) are present, and at least two of the n printing engines, each containing a toner transferring element with a longitudinal axis in the direction of width (WPE), are located so that the longitudinal axis do not coincide. Preferably the printing engines are electro(stato)graphic engines, especially Direct Electrostatic Printing (DEP) engines or electrophotographic engines.
