摘要： Disclosed is a printer in which the driving time of its printer head (10) is determined based on a printer head driving mode selected as a result of control commands interpreted by a control command interpreter (45) and the actual driving voltage Vp used for driving the printer head, and printing is performed according to the determined driving time. The purpose is to set the driving time of the printer head (10) to a time suited to both the used type of recording paper and the actual head driving voltage.

摘要： A print controller apparatus and method thereof for controlling the movement of a printhead assembly including a carriage (7), printhead (1), and head pins. First and second moving times of the carriage moving from first and second predetermined distances and a difference between these moving times are determined. The carriage at a third predetermined distance is then determined based on the first and second moving times and the difference of the moving times. A basic timing signal corresponding to the current print mode is generated in accordance with the current moving time of the carriage (7). A correction value is then computed based on the current moving time of the carriage (7) and from a preceding detected moving time which equals a predetermined time the printhead (1) arrives at the printing paper. The basic timing signal is corrected using the correction value to thereby generate a print timing signal. In accordance with a speed signal being of an inverse proportion to the current moving speed of the carriage (7) and with a preceding computed print timing signal, a drive signal in proportion to the speed signal causes the head pin to make contact with the printing paper for a corresponding amount of time.

摘要： In a wire dot printer having a wire-dot print head provided with wire drive elements disposed in sequence, the energization of the respective wire drive elements is controlled in accordance with print data supplied for respective drive elements and a drive time signal (DT1-n, DT1-n) supplied in common to a plurality of the drive elements. Detection is made, for each drive element, whether or not an adjacent drive element is energized, in accordance with the print data corresponding to the adjacent drive element, and the energization time for the particular drive element is controlled in accordance with the result of the detection.

摘要： Bei einer Einrichtung für die Temperaturüberwachung eines Druckkopfes (20) oder einer Hammerbank der Elektromagnetspulenbauart wird ein Schaltsignal entweder für das Abschalten des Druckkopfes (20) oder für eine Senkung der Betriebsfrequenz oder für die Ein-Ausschalt-Steuerung eines Lüftermotors verwendet. Um eine genauere, schnellere und individuelle Meßwertermittlung zu erzielen, wird vorgeschlagen, daß die jedem Druckelement (1) zugeordnete Elektromagnetspule (3) jeweils während einer Bestromungspause an eine Konstantstromquelle (Up) anschaltbar ist, daß ein Spannungsabfall (Us) an der Elektromagnetspule (3) ein die Temperaturgrenze festlegendes Referenzsignal (26) an einem Komparator (27) erzeugt, daß die Referenzspannung (Uref) als binäres Logiksignal in einen Datenzwischenspeicher (30) übernommen wird und daß das Logiksignal als Steuersignal für eine Temperatursenkung im Druckkopf (20) dient.

摘要： Control circuit for a dot matrix printing head of the permanent magnetic type or symple electromagnet type, wherein a printing element (16, 17) is subjected to a variable magnetic flux, owing to an energization current and/or to a movable armature movement, which causes an energization current to be established in the printing element for its actuation, to be switched off for the deactivation of the printing element and which thereafter establishes a shorting path letting a current induced in the printing element by mangetic flux changes due to the movable armature movement, flow in the printing element, with damping effect on the armature movement.

摘要： A dot-matrix printer can register dot character patterns input through an external unit (11). It has a circuit (17) for correcting a dot character pattern. This circuit (17) checks a dot character pattern stored in a buffer memory (13) to determined whether any two adjacent dots of the pattern which are arranged in the printing direction contact or not. If the dots contact, one of them is erased, thus correcting the dot character pattern. The corrected dot character pattern is stored in a character generator (18). The corrected pattern is supplied from the character generator (18) to a drive circuit (20). The drive circuit (20) drives a print head, etc., whereby the dot character corresponding to the pattern read from the character generator is printed.
