である。Detailed Description of the Invention (1) Technical Field of the Invention The present invention prints the same print data multiple times and compares the print quality in order to confirm the stable normality of the mechanism and operation of the print unit of a print printer. This relates to a printing quality confirmation method.

2行目ア〜オを印字する。(2) Prior Art and Problems Conventionally, as part of the manufacturing test for printing printers, such as serial dot printers, identical printers have been A method has been adopted in which the print data is printed a plurality of times, for example twice, and the print quality is compared. FIG. 1 shows an example of a test system, in which a dot printer under test 10 controlled by a terminal controller (TC) 1 is shown. That is, test data is sent from the tester 2 in the T//c1 to the device controller 11 in the serial dot printer 10 under test via the device controller 3. In response to an operator's instruction from the keyboard 12, the paper feed mechanism 14 inserts, for example, journal paper into the dot printer 16, and one of the test data from the device controller 11 is inserted.
Print a line. When one line is completed, a line break is made and one line of the same test data is printed backwards. Figure 2 shows 1 in this case.
This is an example. After printing 1 to 0 on the first line, print a line feed and print 1 to 0 on the second line. Next, after printing A to O on the first line, change the line and print A to O on the second line. Print.
このように同一データを2行に印字したものを上下比較

ールの破損等に起因する欠陥を抽出し、印字品質を確認
する。In this way, the same data printed on two lines is compared vertically, and defects caused by typos, omissions, missing dots, extra dots, damage to the type wheel, etc. are extracted, and the print quality is checked.
すなわち、両者とも同一欠陥が表われる場合と一方のみ
に表われる場合があり、これによシ正常性と安定性が判
定できる。That is, there are cases where the same defect appears in both cases, and cases where it appears only in one, and the normality and stability can be determined based on this.
しかし、上下の印字文字を比較することは、頭の中で両
者を重ね合せることになるので、その判断はオペレータ
にとってかなシ大きな負担となっている。However, comparing the upper and lower printed characters means overlapping the two in one's head, which puts a heavy burden on the operator.
また1行目と2行目のずれは、この比較方法では正確把
握できない。Furthermore, the deviation between the first and second lines cannot be accurately determined using this comparison method.

供することである。(3) Purpose of the Invention The purpose of the present invention is to confirm the stable normality of the mechanism and operation of the printing section of a printing printer. It is an object of the present invention to provide a printing quality confirmation method that also facilitates the determination of deviations.
(4)発明の構成
前記目的を達成するため、本発明の印字品質確認方式は

のである。(4) Structure of the Invention In order to achieve the above object, the printing quality confirmation method of the present invention is a printing quality confirmation method in which the same printing data is printed multiple times and the printing quality is compared. The present invention is characterized in that a means for overprinting is provided, and the quality is confirmed by the color of the overprinted characters.

のである。(5) Embodiment of the Invention FIG. 1 shows a test system of the present invention, and portions different from the conventional example described above are shown with diagonal lines. In the test method of the present invention, firstly, test data for one line is given twice from the tester 2, but the procedure program 4 is different. The second is to operate in conjunction with this procedure.
This is because a color ribbon feed mechanism 15 is provided. In other words, the procedure is to print one line in the forward direction on the ribbon of the first color, then switch to the ribbon of the second color without starting a line, and print the same print data in the reverse direction. It is.
第3図は本発明の試験方法の具体例による説明図であシ
、第2図と同じジャーナル上の印字例を示す。FIG. 3 is an explanatory diagram of a specific example of the test method of the present invention, and shows an example of printing on the same journal as in FIG. 2.
同図において、まず赤リボンで1〜0を印字し、次に黒
リボンで同じ1〜0を逆行させて重ね印字する。ア〜オ
も同様である。また、要すれば印字例を変えてさらに複
数行につき印字を行なう。In the figure, 1 to 0 are first printed with a red ribbon, and then the same 1 to 0 are printed in reverse using a black ribbon. The same goes for A~O. Further, if necessary, the printing example is changed and printing is performed for a plurality of lines.
オペレータはこれらの結果をチェックし、赤黒両方の欠
けた部分、余分の印字、赤色部分のみ。The operator checks these results and detects missing parts in both red and black, excess printing, and only red parts.
黒色部分のみ、赤黒のずれを調べることによシ、印字機
構の調整欠陥や安定性についての分析を行なうことがで
きる。By examining the deviation between red and black only in the black area, it is possible to analyze the adjustment defects and stability of the printing mechanism.
(6)発明の詳細
な説明したように、本発明によれば、印字プリンタの印
字部の機構と動作の安定した正常性を。(6) As described in detail, the present invention provides stable normality of the mechanism and operation of the printing section of a printing printer.
確認するため、同一印字データを正方向と逆方向に色を
変えて重ね印字させるようにしたものである。これによ
り、2回の印字の重なシの有無とずれが一目して判別で
きるから、機構の欠陥や調整不良の判別が極めて容易と
なる。とくに、正逆2回の印字ずれは判然と認識される
。さらに第2図と第6図の比較で明らかなように、印字
用紙の節約になるという利点も挙げることができる。In order to confirm this, the same print data is overprinted in different colors in the forward and reverse directions. As a result, it is possible to determine at a glance whether or not there is an overlap between the two printings, and therefore it is extremely easy to determine whether there is a defect in the mechanism or a maladjustment. In particular, two print shifts in forward and reverse directions are clearly recognized. Furthermore, as is clear from the comparison between FIG. 2 and FIG. 6, there is also the advantage of saving printing paper.
