Abstract
Description
Die auf dem Markt befindlichen Drucker, die Daten von einem Computer, Meßwerterfassungssystem, oder ähnlichen Einrichtungen auf elektrischem Wege digital verschlüsselt erhalten, drucken sie gewöhnlich auf Endlospapier aus. Sie haben einen Druckkopf und beschreiben immer nur die Vorderseite des Papiers.The printers on the market, the data from one Computer, data acquisition system, or similar devices digitally encrypted electronically received, they usually print out on continuous paper. they have a printhead and only ever describe them Front of the paper.
Der vorgeschlagene Drucker besitzt zwei Druckköpfe, die so angeordnet sind, daß mit ihnen gleichzeitig die Vorderseite und die Rückseite des Endlospapiers beschrieben werden kann. Beide Druckköpfe sind mit Schlitten und Antriebsmotor ausgerüstet und sie bewegen sich, unabhängig voneinander, in Zeilenrichtung.The proposed printer has two printheads are arranged that with them the front and the back of the fanfold paper can be written on. Both printheads are equipped with a carriage and a drive motor equipped and they move in independently Row direction.
In Fig. 1 ist die einfachste Anordnung gezeigt, die bei Druckern möglich ist, bei denen der Druckkopf berührungslos arbeitet und kein Farbband braucht, z. B. bei Tintenstrahldruckern. Für Nadeldrucker, die durch Anschlag ihrer Drucknadeln mit Hilfe eines Farbbandes das Papier bedrucken, ist die Anordnung in Fig. 2 schon etwas komplizierter. Es sind Anschlaglager notwendig und, falls die Druckköpfe in gleicher Höhe angebracht sein sollen, erfordert die Papierführung zum 2. Druckkopf, der die Rückseite des Endlospapiers beschreibt, Umlenkleisten.In Fig. 1 the simplest arrangement is shown, which is possible in printers in which the print head works without contact and does not need an ink ribbon, e.g. B. in inkjet printers. The arrangement in FIG. 2 is somewhat more complicated for dot matrix printers which print on the paper by means of an ink ribbon by striking their printing needles. Stop bearings are necessary and, if the printheads are to be attached at the same height, the paper guide to the second printhead, which describes the back of the continuous paper, requires deflection strips.
Die vorgeschlagene Ausführung des Druckers reduziert den Papierverbrauch auf die Hälfte und dadurch auch die Papierkosten. Ebenfalls verringert sich der Platzbedarf für die Ablage beträchtlich. Ein weiterer wichtiger Vorteil ist die Steigerung der Ausdruckgeschwindigkeit auf fast das Doppelte.The proposed design of the printer reduces the Paper consumption by half and therefore also that Paper costs. The space required for the filing considerable. Another important advantage is the increase in print speed to almost that Double.
Als Nachteil wäre zu erwähnen, daß bei Betrieb mit 2 Druckköpfen keine Durchschläge angefertigt werden können und daß Einzelblatteinzug kaum möglich ist.As a disadvantage it should be mentioned that when operating with 2nd No printouts can be made to printheads and that single sheet feeding is hardly possible.
Mit einem Schalter kann die Tätigkeit des zweiten Druckkopfes außer Betrieb gesetzt werden. Wenn dann noch das Papier so eingezogen wird, wie auf Fig. 2 gestrichelt angedeutet ist, kann der Drucker im vollen Umfang alle Funktionen eines Druckers mit nur einem Druckkopf ausführen. Dann sind Durchschläge und mit Zusatzeinrichtung auch Einzelblatteinzug, möglich. Bei Funktionsstörung des Druckkopfes kann der 2. Druckkopf als Austauschdruckkopf verwendet werden. Dadurch ergibt sich eine höhere Betriebssicherheit.With a switch the activity of the second printhead can be put out of operation. If the paper is then drawn in as indicated by the broken line in FIG. 2, the printer can perform all of the functions of a printer with only one print head. Then copies and, with additional equipment, single sheet feeding are possible. If the print head malfunctions, the 2nd print head can be used as a replacement print head. This results in higher operational reliability.
Die Daten der Datenverarbeitungsanlage werden zum Drucker auf die gleiche Weise geschickt, wie bei einem Drucker mit nur einem Druckkopf. Nur ein Grundsatz muß eingehalten werden: Der Zeilenabstand muß im ganzen Text gleichbleiben, da der Zeilenvorschub gemeinsam für die Vorderseite und Rückseite vorgenommen wird.The data from the data processing system are sent to the printer sent the same way as with a printer with only a printhead. Only one principle has to be followed: The line spacing must remain the same throughout the text, since the Line feed together for the front and back is made.
Die ankommenden Daten werden vom Betriebssystem des Druckers in 2 Pufferspeicher aufgeteilt, und zwar so, daß die Daten für die Seiten 1, 3, 5 usw. in den Speicher 1 und die Daten für die Seiten 2, 4, 6 usw. in den Speicher 2 kommen. Die Speicher sind vom Typ FIFO (First In, First Out). The incoming data is divided into 2 buffers by the operating system of the printer in such a way that the data for pages 1, 3, 5 etc. in memory 1 and the data for pages 2, 4, 6 etc. in memory 2 come. The memories are of the FIFO (First In, First Out) type.
Der Ausdruck kann erst beginnen, wenn die Datenverarbeitungsanlage die Daten für die ganze Seite 1 und einige Zeilen der Seite 2 in die Pufferspeicher des Druckers geliefert hat. Im Falle eines Druckers gemäß Fig. 1 beginnt dann der Ausdruck von Seite 1 und 2 gleichzeitig. Bei der Ausführung des Druckers nach Fig. 2 verzögert das Betriebssystem des Druckers den Beginn des Ausdruckes der Seite 2 (der Rückseite) solange, bis sie an der Druckposition des 2. Druckkopfes erscheint.The printout can only begin when the data processing system has delivered the data for the entire page 1 and a few lines of page 2 into the buffer memory of the printer. In the case of a printer according to FIG. 1, the printing of pages 1 and 2 then begins simultaneously. In the embodiment of the printer of Fig. 2, the operating system of the printer delays the onset of expression of page 2 (the back) until it appears at the printing position of the second print head.
Da die Schlitten beider Druckköpfe mit einem selbständigen Antriebsmotor ausgestattet sind, können beide Zeilen unabhängig voneinander, auch mit verschiedenen Geschwindigkeiten, geschrieben werden. Der Betrieb beider Druckköpfe ist bidirektional. Das Betriebssystem gibt den Impuls an den gemeinsamen Papiervorschubmotor zum Weiterschalten zur nächsten Zeile erst dann, wenn in beiden Zeilen das Zeilenende erreicht ist, oder der Steuerimpuls "Neue Zeile" ansteht.Since the carriage of both printheads with an independent Drive motor are equipped, both lines independently of each other, even at different speeds, to be written. The operation of both printheads is bidirectional. The operating system gives the impulse to the common paper feed motor to advance to next line only if in both lines the Line end is reached, or the control impulse "new line" pending.
Wenn am Ende eines Ausdruckes der Pufferspeicher für die Vorderseite, oder Rückseite schon leer ist, erfolgt der Papiervorschub nur noch nach dem Bedarf des noch vollen Speichers.If at the end of a printout the buffer memory for the Front, or back is already empty, the Paper feed only according to the needs of the full one Memory.
