Description

TECHNICAL FIELD The present invention relates to a test pattern printing method in a printer.

[Conventional technology]

Printers that use single-cut sheets include non-printing aging tests that check spacing and line feed systems, all-character print tests that check used character patterns and print heads, and equilibrium levels and the first line print position of media. It has a function to perform fixed character printing test, etc. to check the amount of printing deviation.

Although these tests conventionally operate independently by some means such as a test branch switch, the fixed character printing test among them plays a particularly important role for a printer using a cut sheet. The reason is that, generally, a sprocket hole for line feed is not formed in a single form, and a line feed operation of the single form is performed by a friction roller of the printer. That is, the line feed operation by the friction roller is
This is because the slips are more likely to slip than in the line feed operation using the sprocket pin, and this slip causes line feed misalignment and skew of the slips.

Therefore, in general, the operation of a single form is fixed information such as customer name,
Since it is a sheet for printing the contents of the deposit balance, the deposit amount, etc., there arises a disadvantage that the information of the deposit amount column of the next line is printed in the balance column of the preceding line due to the line feed misalignment and skew. Therefore, in order to avoid such inconvenience, every line is printed on the test cut sheet, and the number of lines is checked.
It can be seen that the fixed character print test for checking the amount of blank space and the number of print lines from the leading edge and the trailing edge of the cut sheet and the balance degree check are important from the meaning different from the all character print test.

In order to perform the above-mentioned fixed character printing test and all character printing test, conventionally, as shown in the flowchart of FIG. 2, a test branch switch is used to manually perform a test branch between a fixed character printing test and an all character printing test. When the all-character print test is selected, all-character print processing is performed and the all-character confirmation print pattern is printed on the single-cut sheet 1 as shown in FIG.

If you want to perform a fixed character print test subsequently, manually select the fixed character print test with a test branch switch or the like to perform the H character print process, and print the equilibrium degree confirmation print pattern on the single-cut sheet 2 as shown in FIG. Is printed.

In the above-mentioned conventional example, the all-character printing test and the fixed-character printing test were performed by two manual branching operations using the test branching switch or the like. A conventional example is shown in the flowchart of FIG.

In this conventional example, a fixed character printing process is performed on the first sheet to print a print pattern for confirming all characters on the first sheet 1 as shown in FIG. Character printing processing is performed to print the equilibrium level confirmation print pattern on the single-cut sheet 2 as shown in FIG.

[Problems to be solved by the invention]

However, in each of the conventional examples as described above, the all-character printing test and the fixed-character printing test are performed separately for each single sheet, so that the printing output time for all-character printing and balance printing increases and the confirmation time increases. There is a problem that will be longer.

The present invention has been made to solve the above problems, and an object of the present invention is to perform a fixed character print test and an all character print test on a single cut sheet to speed up the print test and print. The purpose is to shorten the test operation program and reduce the memory capacity for storing the program.

[Means for solving problems]

To achieve this object, the present invention provides a test pattern printing method for a printer in which a friction roller is used to perform line feed on a single-cut sheet and a print head prints on the single-cut sheet. A print pattern for checking the degree of equilibrium is printed with the same character to check the line feed misalignment and skew of the single sheet on the entire line of the line and the last line, and the state of the character pattern used by the printer is displayed on the other lines in the print area. It is characterized by printing a print pattern for checking all characters by using all used characters for checking the state of the print head.

[Action]

According to the present invention by such a method, by checking the all-character confirmation print pattern printed on the middle line of one cut sheet,
It is possible to check the status of the used character patterns such as character data status, character loss and print density, and the status of the print head, and the print position of the equilibrium confirmation print pattern printed on the first and last lines. It is possible to check whether there is a line feed misalignment caused by the friction roller slip by checking, and check the balance degree of the friction roller by checking the balance degree of the balance degree confirmation print pattern printed on the first line and the last line. The skew due to slip can be checked.

Therefore, according to this, since it is possible to check the state of the used character pattern and the state of the print head and the line feed misalignment and the skew with one cut sheet, the test time and the test result confirmation time can be shortened. At the same time, since the test can be performed by one test processing program, it is possible to reduce the capacity of the memory that stores the test processing program.

〔Example〕

Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 and 6.

FIG. 1 is a plan view showing an example of printing all character confirmation print patterns and balance degree confirmation print patterns according to an embodiment of the present invention,
FIG. 6 is an example of a flow chart of the test pattern printing method according to the present invention.

In the flowchart of FIG. 6, when the printer test is started, the line number counter and steps are cleared,
When this step becomes STEP = 00, first, as shown in the first line of FIG. 1, on the first line of the single-cut sheet 1, a print pattern for confirming the degree of balance, that is, H in this embodiment, is printed as a fixed character print test. When printing is completed, the step is updated, that is, ST
Set EP = 01 to determine if the test is over.

Here, if the test is completed, the printer is stopped. If the test is continued, the process returns to the step branch again, and since the step is STEP = 01 at this time, the next line, that is, the even-numbered second line is the all-character print test, and all characters are shifted by the shift-in print. After printing the confirmation print pattern and updating the line number counter by one, the next line, that is, the odd-numbered third line, is not the final line, so the shift-out print prints the entire character confirmation print pattern again The above-described shift-in printing and shift-out printing are alternately repeated until the counter is updated by one and the next row becomes the final row. And when the next line becomes the last line, update one step
Set STEP = 0 to determine if the test is over.

Here, if the test is completed, the printer is stopped. If the test is continued, the process returns to the step branch again, and since the step is STEP = 02 at this time, a fixed character, that is, H in this embodiment, is printed on the last line as shown in the last line of FIG. . When printing is completed, the line counter is cleared and the steps are cleared, and STEP
= 00, it is determined whether the test is completed.

Here, if the test is completed, the printer is stopped. If the test is continued, the printing operation described above is repeated for the next cut sheet.

FIG. 7 shows another example of the flow chart of the test pattern printing method according to the present invention. In contrast to the flow chart of FIG. 6 which broadens the concept of the step management method, the flow chart of FIG. The concept is expanded in columns and repeated processing is performed, and the processing of STEP = 01 shown in FIG. 6 is performed.

The flowchart shown in FIG. 7 will be described below. First,
When the printer test is started, the line number counter is cleared, and as shown in the first line of the voucher 3 shown in FIG. 1 as an embodiment, the balance degree confirmation print pattern, that is, H is printed in this embodiment. , When the printing is finished, it is judged whether the test is finished.

Now, if the test ends, the printer stops. If the test is continued, the next line, that is, the even-numbered second line is printed by shift-in printing to check all characters and the line number counter is updated by one. If the eye is not the last line, decide whether to end the test next.

If the test ends here, the printer will stop. If the test is continued, the next line, that is, the odd-numbered third line is printed out by shift-out printing again for all character confirmation print pattern, the line number counter is updated by 1 and the next line becomes the last line. Up to the shift-in printing operation to the shift-out printing operation are repeated.

When the next line becomes the last line, a fixed character, that is, H in this embodiment, is printed on the last line as shown in the last line of FIG. 1, and the printer stops.

The above-described flowchart shown in FIG. 6 does not have the concept of steps as compared with the flowchart shown in FIG. 2, so that the program can be simplified.

In addition, in each of the above-mentioned examples, for convenience of ending the test,
Although the judgment is made every time the printing of one line is completed, the judgment of the completion of printing may be made during the printing of each line. Further, in each of the above-mentioned examples, the print pattern for confirming all characters is printed on the line between the first line and the last line, but the print pattern for confirming all characters is printed at the beginning and end of each line. As shown in FIG. 1, printing the letter H of the equilibrium degree confirmation print pattern has the advantage that the left and right equilibrium degree can be confirmed. The combination of characters and the like printed on the cut sheet 3 is not limited to the combination shown in FIG.

Further, in the above embodiment, as an example of a fixed character, H
Although characters are used, any characters such as +, one, two, etc. may be used as long as the degree of balance can be confirmed. Further, in the above embodiment, the equilibrium degree confirmation print pattern is printed only on the first line and the last line, but it is not limited to the first line and the last line.

〔The invention's effect〕

As described above, according to the present invention, the print pattern for the equilibrium degree confirmation by the same character for checking the line feed deviation and skew of the cut sheet at least on the entire first line and the last line of the print area of one cut sheet. Is printed, and a print pattern for checking all characters by all used characters for checking the state of the used character pattern of the printer and the state of the print head is printed on the other lines in the print area. By checking the print pattern for checking all characters printed on the middle line of a single sheet, it is possible to check the status of the character data such as character data, character loss and print density, and the status of the print head. By checking the printing position of the equilibrium degree confirmation print pattern printed on the first and last lines, it is possible to check whether there is a line feed misalignment due to the friction roller slip. It is possible to check the skew due to the slip of the friction roller by checking the balance degree of the print patterns for confirming the balance degree printed on the first line and the last line. The effect of being able to be obtained is obtained.

Therefore, according to this, since it is possible to check the state of the used character pattern and the state of the print head and the line feed misalignment and the skew with one cut sheet, the test time and the test result confirmation time can be shortened. At the same time, since the test can be performed by one test processing program, it is possible to reduce the capacity of the memory that stores the test processing program.
