Definitions
- the invention relates to a method for displaying characters according to the preamble of claim 1. Furthermore, the invention relates to an arrangement for performing the method.
- first and second movements of the printing unit can match or be opposite to each other.
- the printing unit is returned to its starting position and then the second movement is carried out, while in the second case the second part of the characters is printed while the printing unit is being returned.
- Such a method has the disadvantage that, due to inaccuracies in the advance of the record carrier, an offset can occur within the characters and the legibility of the individual characters is thereby impaired.
- the invention is therefore based on the object of specifying a method and an arrangement in the use of which an offset-free printing of the lines of characters is achieved even if the line height is greater than the height assigned to a printing unit and if two consecutive movements for printing the characters of the printing unit with an intermediate feed of the recording medium are required.
- the object is achieved in the method of the type mentioned by the features specified in the characterizing part of claim 1.
- the method according to the present invention has the advantage that a large line height is achieved with a relatively small printing unit. This results, for example, when using a mosaic printing unit, a smaller number of printing elements, so that the printing unit can be produced inexpensively. Due to the lower mass of the printing unit, less energy is required for the movement of the printing unit. Inaccuracies in the displacement of the record carrier relative to the printing unit do not have an effect as an offset within the lines of the characters, but at most from character to character. This does not affect the legibility of the individual characters. Furthermore, the method according to the invention has the advantage that a feed gear required for the movement of the record carrier can be constructed inexpensively, since, for example, no tooth play adjustment and no rest points are required. To print the characters are compared to printing with a corresponding larger printing unit At least two movements of the printing unit are required, but a high printing speed can also be achieved with the method according to the invention, since larger tolerances can be permitted during printing.
- Printing can be unidirectional or bidirectional.
- unidirectional printing the printing unit is returned to a starting position after the first movement and the second movement is carried out after the partial advance of the recording medium.
- bidirectional printing the second movement is carried out immediately after the first movement and the partial advance of the record carrier.
- it is also possible to carry out the partial feed if a character with a middle area or a middle area and an upper length is followed by a character with an undersize.
- the ratio of the line height to the center area is approximately 3: 1.
- this partial feed corresponds, for example, to the height assigned to half the number of printing elements.
- the mosaic printing unit is preferably designed as a needle printing unit or as an ink printing unit.
- An advantageous arrangement for carrying out the method contains a control unit which emits a control signal which triggers the first movement to a carriage control and then feeds the characters to be printed during the first movement to the printing unit, which then emits a first feed signal which triggers the partial feed to a feed control and which then outputs a signal which triggers the second movement of the printing unit to the carriage control and which then supplies the characters to be printed during the second movement to the printing unit.
- the characters Z1 to Z3 shown in FIG. 1 are, for example, Arabic characters, the lines of which are represented in a half-step grid by a printing unit DW.
- the printing unit DW contains nine printing elements D1 to D9, which are arranged adjacent to one another.
- the height assigned to the sum of the printing elements D1 to D9 is smaller than the line height H.
- the characters Z1 and Z2 have a central area M and an upper length 0, while the character Z3 has a central area M and a lower length U. Characters, whose coherent lines have both descenders and ascenders, are not intended for the Arabic characters, similar to the Latin characters.
- the characters Z1 and Z2 as well as further characters (not shown) of the line are printed, which only have a central area M or a central area M and / or at least an upper length 0.
- the word "sign" is understood to mean the lines of the signs, which can be linear or point-shaped.
- the upper lengths 0 are printed by the printing elements D1 to D4 and the central areas M are printed by the printing elements D5 to D9.
- At the end of the line there is a partial advance of the recording medium relative to the printing unit DW in such a way that during a second movement B2 those characters can be printed which have a central area M and a short length U.
- the central areas M are printed by the printing elements D1 to D5 and the descenders by the printing elements D6 to D9.
- a return of the printing unit DW to its starting position is required after the partial feed and the second movement B2 takes place in the same direction as the first movement B1. It is also possible to print the characters bidirectionally. In this case, the direction of movement B2 is opposite to the direction of movement B1 and it is not necessary to return the printing unit DW to its starting position. After all characters have been printed during movement B2, a line feed is carried out in order to create a line spacing from the next line. A movement B1 of the printing unit DW is then carried out again in order to print the next characters.
- the height of the partial feed usually corresponds to the height of the upper length O. In a mosaic printing unit, for example, it is approximately equal to the height of half the number of printing elements. This results in a ratio of the row height H to the height of the center area of 3: 1. This relationship proves particularly useful for the representation of Arabic characters.
- the printing unit DW is arranged on a printer carriage W, which is moved along a platen roller SW using a motor M1, preferably a stepping motor.
- the platen roller SW is driven by a motor M2, preferably also a stepper motor, via a countershaft.
- a recording medium AT is placed around the platen roller SW, on which the characters are printed.
- the characters are entered via a keyboard TA, via a long-distance line FL connected to a line adapter LA or via a memory SP.
- the entered characters are fed to a control unit ST, which controls the timing of all processes and preferably contains a microcomputer.
- the control unit ST is connected to a printer control DS, which contains a carriage control WS connected to the motor M1 and a feed control VS connected to the motor M2.
- the printer carriage W with the printing unit DW is in a starting position on the edge of the record carrier AT.
- the characters of a line entered via the keyboard TA, the memory SP or the line adapter LA are first displayed on a display unit AE.
- the control unit ST sends a signal S1 to the carriage controller WS which triggers a first movement B1 of the printing unit DW in the horizontal direction.
- the control unit ST sends all the characters Z, which contain a central area M and at least one upper length 0, to the printing unit DW, which represents these characters on the record carrier AT.
- the control unit ST When the end of the line has been reached, the control unit ST emits a first feed signal V1 to the feed control VS, which causes a partial feed of the record carrier AT perpendicular to the line direction using the motor M1.
- the height of the partial feed is dimensioned such that all characters with a central area M and a short length U can now be displayed.
- the control unit ST emits a signal S2 to the carriage control WS, which triggers the second movement B2 of the printing unit DW, during which the printing unit DW is returned to the starting position and at the same time prints the corresponding characters Z with short lengths U.
- the control unit ST After all characters of a line have been printed, the control unit ST generates a further feed signal V2 which triggers a line feed of the record carrier AT.
- unidirectional printing can also take place.
- the printing unit DW is returned to the starting position after printing the characters with a central area M and at least an upper length 0 and then the characters with a central area and a lower length U are printed in the same direction of movement. Then there is a return to the starting position.
- the partial feed and the line feed can take place either at the end of the line, at the beginning of the line or during the return of the printing unit DW.
- Those characters that only have a central area M are preferably also printed during the first movement B1 of the printing unit DW. In principle, however, it is also possible to print them during the second movement B2.
- the method and the arrangement are suitable not only for the representation of characters of the Arabic or similar script, but also for the representation of the Latin script.
- the only exception is the character "j", in which the dot is printed during the first movement B1 and the actual character during the movement B2. In any case, it is ensured that there is no offset within the characters. As a result of component tolerances, an offset between the individual characters can occur at best.
