When packages in the existing logistics are transferred, logistics intermediate information labels need to be printed for multiple times, and the printing labels are pasted for multiple times.

In order to solve the problems, the invention provides a printing method for printing logistics information in a logistics process, so that one-time printing is changed into multiple times of printing in an intermediate link, pasting actions are reduced, paper is saved, and working efficiency and accuracy are improved.

Fig. 1 schematically illustrates a printing method according to an exemplary embodiment of the present invention. The method provided by the embodiment of the invention can be executed by any electronic equipment with computer processing capability, such as a terminal device and/or a server. Referring to fig. 1, the printing method is suitable for printing information in a logistics process, and may include the following steps:

step S102, after a printer is placed or pressed at a first printing position on printing paper, acquiring a first printing instruction, wherein the printing paper is thermal paper and is pasted on a commodity;

step S104, printing first printing content on the printing paper according to the first printing instruction;

step S106, after the printer is placed or pressed at a second printing position on the printing paper, acquiring a second printing instruction;

step S108, according to the second printing instruction, printing second printing content on the printing paper;

According to the technical scheme of the embodiment of the invention, after the printer is placed or pressed on the printing paper, the printing instruction is obtained, and the printing content is printed on the printing paper according to the printing instruction, so that one-time printing is changed into multiple times of printing in an intermediate link, the pasting action is reduced, the paper is saved, and the working efficiency and the accuracy are improved.

In step S102, a first print instruction is acquired after the printer is placed or pressed at a first print position on a print sheet, which is a thermal paper and is pasted on a commercial product.

In this step, the terminal device and/or the server acquires the first print instruction after the printer is placed or pressed at the first print position on the print sheet, which is the thermal paper and is attached to the commercial product. In one embodiment, the printing paper has a pasting function, the printing paper is pasted on a commodity (such as a package in a logistics process), the printing paper has basic description information (such as basic data information fixed on the commodity in the package), wherein after a printer is placed or pressed on a first printing position on the printing paper, a first printing instruction is acquired, and the printing instruction comprises:

acquiring a first printing instruction after the printer is placed or overlaid on the first printing position on a blank or blank square on the printing paper to be printed. In one embodiment, the first printing instruction is, for example, an operation action performed by operating a key on the printer after a worker places or presses the printer on a blank space or a blank square to be printed on the printing paper, and the terminal device and/or the server obtains the first printing instruction after detecting the operation of the worker. In one embodiment, the printer is a thermal printer, and the printing device of the printer comprises N rows of heating elements, wherein N is greater than or equal to 2.

In step S104, first print content is printed on the printing paper according to the first print instruction.

In this step, the terminal device and/or the server prints the first print content on the print sheet according to the first print instruction.

and controlling a heating element of the printer corresponding to the region of the printing paper where the characters need to be printed to heat according to the region of the printing paper where the characters need to be printed, thereby realizing the printing of the first printing content. In one embodiment, the area of the printing paper where the text needs to be printed is a part which is displayed as text or a pattern after the printing is completed.

In one embodiment, the printing method further comprises: when the first printing is fault-tolerant, acquiring an erasing instruction after the printer is placed or pressed on the first printing content;

For example, after printing is completed, the worker finds that the printed information is wrong, and at this time, an erasing operation needs to be performed. The worker can place or press the printer on the wrong first printing content, operate the keys on the printer to execute operation actions, and erase the wrong printing content from the printing paper.

and according to the erasing instruction, performing coating output coverage to enable the printing paper to have the first printing content to recover blank. The coating output coverage means that the existing printing content is covered with a thermal sensitive layer, so that the printing content has the effect of reuse.

according to the erasing instruction, the coating output covering is performed at the thermosensitive position where the first printing content is detected so that the portion of the printing paper having the first printing content is blank. In this embodiment, it may be that the area printed with the letters and patterns where the error is detected operates to perform the erasing operation.

according to the erasing instruction, the thermosensitive position of the first printed content is detected, so that a heating element of the printer corresponding to the area of the first printed content is heated, and the erasing of the first printed content is realized. In this embodiment, it may be that all areas covered by the printer printhead are operated to perform the erasing operation.

In step S106, a second print instruction is acquired after the printer is placed or pressed at a second print position on the printing paper.

In this step, the terminal device and/or the server acquires a second print instruction after the printer is placed or pressed at a second print position on the printing paper.

In step S108, according to the second print instruction, second print content is printed on the printing paper.

In this step, the terminal device and/or the server prints second print content on the print paper according to the second print instruction.

Fig. 2 shows a prior art logistics commodity production printing process.

Referring to fig. 2, the whole process of the existing production of large commodities mainly comprises: warehousing, ex-warehouse, sorting and appropriate delivery.

Referring to fig. 2, in the case of the prior art, roughly one real object (package) needs to be printed when entering or leaving the warehouse, there are:

commodity information: commodity code, commodity name, serial number, batch number;

order information: order number, waybill number, consignee information, etc.;

production information: delivery dock number, pick-up serial number, etc.

In practice, in a package label, since the printed data information is data generated in different production links, if all data needs to be printed correctly and displayed, the data needs to be correctly printed after the last business link is executed, for example:

1. the information is the information which is only available after positioning and dispatching;

2. a picking task sequence number, information which is unique when the picking task is executed;

3. road area information exists after an order is issued;

4. the commodity information and the commodity code label are repeated and are also data which is convenient to store;

and 5, RFID (Radio Frequency identification) service code which is directly printed on the scanned RFID at the time of picking.

It can be seen that the following problems mainly exist in the prior art:

a real object is wrapped in a production link and needs to be printed for at least more than 3 times, so that not only are printing business links and actions increased, but also the problems of paper waste, operation cost increase and the like exist;

the data generated in different business links can be printed and displayed only at the last business node;

the dynamically printed data can only be added in a business operation link and cannot be fixedly stored, so that the printed label information is mistaken when the label is re-printed or replaced, and the re-printing can only be invalidated, for example, the printed RFD information on the package label is invalid when the RFID is replaced and scanned.

Fig. 3 is a schematic flow chart of a technical solution of an embodiment of the present disclosure.

Referring to fig. 3, a printing flow of the dynamic printing apparatus of the present disclosure is used.

From the comparison of fig. 2 and fig. 3, it is found that the flow of the change is:

the pasting action is changed into one-time pasting from a plurality of times;

the printing node is changed from one-time printing to multi-time printing;

the printing data is changed from fixed printing to dynamic addition;

the key technical points for realizing the above process are as follows: the improvement of a printing head of a thermal printer.

FIG. 4 is a schematic view of a printhead of a prior art thermal printer.

Referring to fig. 4, the conventional thermal print head is basically constructed by a row of heating elements, and has a plurality of square dots, each having a size of 0.25mm, and the dots or stripes are displayed on the thermal paper at specific positions controlled by the printer.

Referring to fig. 4, when a conventional printer prints, the printer controls the printing speed of the thermal print head (actually, controls the paper feeding speed of the thermal paper), and the printer controls which heating elements of the thermal print head are heated to display on the thermal paper. Therefore, the existing printing logic is one-time printing.

FIG. 5 is a simplified diagram of the printing effect of a modified thermal print head according to one embodiment of the present disclosure.

Fig. 5 is a modified thermal printing head (a 30 × 30-equivalent master mask, which can be dynamically adjusted and set to match the size of the thermal paper), and the printing principle is different from that in fig. 4: the mother set in fig. 5 is a print head with a determinant two-dimensional typesetting, the printing speed is not required to be controlled by the printer, and the printer can be used for heating the coordinate point of the character to be printed by program control after the printer is placed or pressed on the printing paper, so that the character is displayed on the printing paper.

The print head mode of fig. 5 realizes dynamic data printing capability of 'one-time paste, print at any time'.

The principle of achieving erasable capabilities is consistent with the dynamic printing principle. And only the subsequently generated business operation data is used for the data needing to be erased. If the current package information needs to be replaced by the scanned RFID, the RFID service code needs to be erased and new printing data needs to be added again.

The erase principle can be implemented in two ways:

1. the heat-sensitive coating is subjected to chemical reaction at high temperature, so that the heat-sensitive coating is recovered to be white;

2. the printing device is provided with a thermosensitive coating output capability, and the thermosensitive position with characters is detected to carry out coating output coverage. The coating output coverage means that the existing printing content is covered with a thermal sensitive layer, so that the printing content has the effect of reuse.

The printing system for the present disclosure performs the schema logic and data flow as shown in fig. 6 and 7 below.

FIG. 6 is a flow chart of modified warehousing batch-by-batch printing according to an embodiment of the present disclosure.

FIG. 7 is a flow chart of modified ex-warehouse batch printing according to an embodiment of the present disclosure.

Referring to fig. 6 and 7, it is apparent that the following points are required in production:

if the commodity name in the commodity information is changed during warehousing, erasing and re-printing are needed;

whether the label is consistent with the label when the label is put on a shelf to a corresponding storage position or not, and if the label is inconsistent with the label, the label needs to be erased and reprinted;

when picking the goods, the system mainly comprises a positioning platform, vehicle dispatching order information, task information, RFID information and the like, whether the information is consistent with the label or not is judged, when the information is inconsistent with the label, the label is required to be erased and reprinted, and when the information is not consistent with the label, the label is added in batches.
