Drawings
In order that the present disclosure may be more readily and clearly understood, reference is now made to the following detailed description of the embodiments of the present disclosure taken in conjunction with the accompanying drawings, in which
FIG. 1 is a flowchart of an embodiment of an online printing method of a printer according to the present invention.
Detailed Description
The present invention is further described below in conjunction with the following figures and specific examples so that those skilled in the art may better understand the present invention and practice it, but the examples are not intended to limit the present invention.
Referring to fig. 1, an online printing method for a printer includes the following steps:
step 1: an operator logs in the printer online printing system;
step 2: initializing a printer system;
and step 3: generating a bar code to be printed by utilizing an online printing system of a printer;
and 4, step 4: verifying a bar code to be printed; if the bar code to be printed does not meet the requirements, returning to the step 3;
if the bar code to be printed meets the requirements, executing the step 5;
and 5: comparing the bar codes stored in the database with the local stored bar codes, if the bar codes are consistent, executing the step 6, and if the bar codes are inconsistent, performing correction operation: replacing the database saved bar code with a local saved bar code by taking the local saved bar code as a standard, and executing a step 6 after correction, wherein the database saved bar code is the last bar code saved during the last printing, the local saved bar code is the bar code automatically saved after the last printing is finished, and the comparison of the bar codes can be used for avoiding the influence of the bar code saving error caused by the last printing due to network break or paper jam and the like on the current printing;
step 6: setting a serial number of a bar code to be printed and the number of copies corresponding to the serial number, printing for the first time, and scanning the printed bar code by a high-speed scanner to form a high-speed scanning bar code;
and 7: identifying the high-speed scanning bar code to identify a blank label and a repeated bar code, storing the missing code corresponding to the blank label into a missing code database, and storing the repeated bar code into a repeated code database;
and 8: and printing the missing codes in the missing code database.
Referring to fig. 1, in one embodiment, a login window of an online printing method of a printer communicates with a database to realize functions of registering, modifying a password, logging in and the like, and simultaneously, the name of a login person is displayed on the printing window according to information of the database. The operators are divided into two types of personnel, namely managers and ordinary operators, and the managers have the authority of correcting the current printed bar codes and checking the operation logs after logging in; after logging in, a common operator has the authority of generating and printing the bar code. Through the setting of the authority, printing errors or printing failures caused by improper operation of ordinary operators can be avoided, and the personnel with printing failures can be tracked according to the operation log.
In one embodiment, initializing the printer system includes clearing the memory and detecting the number of bar code sheets. If the initialization is not successful, the initialization can be manually performed, the situation that the printing is repeated due to the fact that the paper is printed successfully such as paper jam in the last time can be avoided by clearing the memory, and waste of paper is reduced. The number of the detected bar code paper is used for limiting the serial number, and if the number of the bar code paper is smaller than the number of the bar codes to be printed, the phenomenon that the number of the bar code paper is insufficient in the printing process and the printing cannot be normally finished occurs.
In one embodiment, the bar code to be printed is generated before printing, and the bar code to be printed is generated by four parameters, such as 68750400000001, wherein the bar code has a length of 14, a type of 75 meters and an aperture code number of 04. The relevant parameters of the table can be identified through the data of the bar code.
In one embodiment, before printing, the barcode to be printed is verified, including verification of the length of the barcode to be printed and verification of parameters of the barcode to be printed, and there may be a situation that a barcode is generated incorrectly in a process of generating the barcode to be printed, for example, a length of the barcode to be printed is increased or decreased compared with a length of a standard barcode to be printed. The condition that the length of the bar code to be printed generates errors can be prevented by verifying the length of the bar code to be printed. Different meter parameter types are different, the situation that the types of the heat meter and the water meter are wrong can occur, and when the bar code of the heat meter is printed, whether the bar code has the water meter type parameter or not needs to be detected; when the bar code of the water meter is printed, whether the bar code has a hot meter type parameter needs to be detected so as to prevent the meter type from being wrong. Parameters in parameter verification of the bar code to be printed comprise a table type, a valve control type, an aperture parameter and a channel parameter.
In one embodiment, comparing the barcode stored in the database with the locally stored barcode, if the barcode comparison is consistent, it indicates that the previous printing is normal printing, then step 6 is executed, and if the barcode comparison is inconsistent, it indicates that the previous printing may be abnormal printing due to problems such as network breaking or paper jam, then a correction operation is performed: and 6, replacing the database saved bar code with a local saved bar code according to the local saved bar code, and executing the step 6 after correction, wherein the database saved bar code is the last bar code saved during the last printing, and the local saved bar code is the bar code automatically saved when the last printing is finished. The bar code can be prevented from being missed due to the problems of network breaking or paper jamming and the like through the comparison of the bar codes.
In one embodiment, the serial number and the number of copies corresponding to the serial number are set, and the first printing is performed while the high-speed scanner scans the printed bar code to form a high-speed scanned bar code. The serial numbers are used for determining printed barcodes, each barcode to be printed corresponds to one serial number, and each serial number corresponds to one serial number. For example, bar code 68750400000001, serial number 3, number of copies 1. Then the printing results are 68750400000001, 68750400000002, 68750400000003, 68750400000004. If the number of copies is 2, the printing results are 68750400000001, 68750400000001, 68750400000002, 68750400000002, 68750400000003, 68750400000003, 68750400000004, 68750400000004. The number of the last bar code to be printed is equal to the number of the first bar code to be printed plus the serial number.
In one embodiment, the high-speed scanning bar code refers to a bar code which is stored while being printed, blank labels and bar codes which are repeatedly printed can be identified by scanning the bar code at a high speed, and if the blank labels exist, the unprinted bar codes can be stored in a missing code database; if the bar code has a duplication code, the duplication code is stored in a duplication code database.
In one embodiment, after the first printing is finished and the high-speed scanning is performed, the continuous printing can print the bar codes in the missing code database, and the printed missing codes can be deleted at the same time. When coincident codes appear, 1 is added on the basis of the last bar code printing for printing again, so that the number of the bar codes needing to be printed is ensured, and the condition of code missing is prevented from appearing again.
The printer online printing method can automatically initialize the system before printing, clear the data left after the last abnormal printing, store and compare different bar codes, prevent the repeated printing condition when restarting, scan the printed bar codes by a high-speed scanner, and re-print the missed bar codes.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the invention may be made without departing from the spirit or scope of the invention.
