Description
Technical Field

Background
Nowadays, with the development of economy, the phenomenon of labeling of commodities gradually appears. The contents of the product such as the identification, price, receipt and the like can be represented by a label, and the label needs to be printed by a printer, so that a label printer is produced. When the label printer prints labels, a label paper printing area of label printing paper is detected, and then label printing is performed in the label paper printing area according to printing contents. The label printing paper is divided into label paper and base paper. The label paper printing area is actually the position area where the label paper is located.
In the prior art, as shown in fig. 1. Fig. 1 is a schematic partial structure diagram of a prior art label printer, and in fig. 1, there are a light source S, a label printing paper L and a sensor a. Wherein the light source S is mounted on a paper compartment cover of the label printer, the sensor A is mounted at a relative position of the light source S, and the light source S and the sensor A are driven by different circuits. When the label printer prints labels, the light source S emits light 1, the light irradiates on the label printing paper L, the sensor A receives light 2 penetrating through the label printing paper L, and voltage corresponding to the light 2 is obtained. Since the label paper and the base paper have different light transmission degrees, the sensor obtains a voltage corresponding to the light 2 when the light 1 is irradiated on the label paper, and the voltage corresponding to the light 2 obtained by the sensor when the light 1 is irradiated on the base paper is also different.

Detailed Description
In order to make the objects, technical solutions and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without any creative effort belong to the protection scope of the present specification.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
The present specification provides a printer including a controller, a light source, a sensor, a photoelectric conversion circuit, a printing element, and a driving circuit. The light source and the sensor are arranged on the same side in a paper bin of the printer, and the controller drives the light source and the sensor through the same driving circuit. In addition, the light source and the sensor can be installed in other positions in the paper bin of the printer except for the paper bin cover, but are not installed on the paper bin cover. As shown in fig. 2.
Fig. 2 is a schematic partial structural diagram of a printer provided in an embodiment of the present specification. In fig. 2, there are a light source O, a sensor B, and a label paper F. The light source O and the sensor B are arranged on the same side of the other positions except the paper bin cover in the paper bin of the printer and are driven by the same driving circuit. Wherein, the light source O emits a light ray l, and the sensor B receives a light ray l' reflected by the light ray l.
Based on the printer shown in fig. 2, the present specification provides a method of label printing, as shown in fig. 3.
Fig. 3 is a schematic diagram of a label printing process provided in an embodiment of the present specification, including:
s100: illuminating label printing paper by a light source, wherein the label printing paper comprises label paper and base paper.
In the embodiment of the specification, a controller in the printer controls the light source to be started, so that the light emitted by the light source irradiates label printing paper, wherein the label printing paper comprises label paper and base paper. The specific structure of the label printing paper F is shown in fig. 4. In fig. 4, a parallelogram indicated by a dotted line is a region of the label paper, and other regions of the label printing paper than the region of the label paper are regions of the base paper. In addition, the label printing paper in the printer is continuously conveyed in one direction in the paper bin, and the position of the light emitted by the light source on the label printing paper is continuously changed along with the movement of the label printing paper.
S102: and receiving reflected light reflected by the label printing paper.
In the embodiments of the present specification, the controller controls the sensor to receive the reflected light reflected by the label printing paper. The surface of the label paper in the label printing paper is rougher relative to the surface of the base paper, so that the reflection capability of the label paper to light is weak, and the reflection capability of the base paper to light is strong.
S104: and converting the reflected light into an electric signal to obtain a voltage corresponding to the reflected light.
In the embodiment of the present specification, the reflected light is converted into an electrical signal according to a preset circuit, and a voltage output by the circuit is obtained. The preset circuit is a photoelectric conversion circuit.
Specifically, the intensity of the reflected light reflected by the label paper and the base paper can be determined according to the intensity of the light reflection capability of the label paper and the base paper in the label printing paper, then the controller controls the photoelectric conversion circuit to convert the reflected light into an electric signal, the voltage corresponding to the reflected light is output through the photoelectric conversion circuit, and whether the position irradiated by the light source is the position of the label paper can be judged according to the voltage corresponding to the reflected light.
S106: and determining the printing starting position of the label paper in the label printing paper according to the voltage corresponding to the reflected light.
In the embodiment of the present specification, as the label printing paper is continuously conveyed, the light source is sometimes irradiated on the label paper, sometimes irradiated on the base paper, sometimes in a transition stage from the label base to the base paper, and sometimes in a transition stage from the base paper to the label paper. In the above four irradiation cases, the voltages corresponding to the reflected light are different. Therefore, the controller can determine the printing start position of the label paper in the label printing paper according to the voltage output by the photoelectric conversion circuit.
Specifically, according to voltages corresponding to reflected light reflected by different printing label paper, the printing starting position of the label paper in the label printing paper can be determined by a method of setting a threshold value. The printing starting position of the label paper in the label printing paper can also be determined through the condition that the voltage corresponding to the reflected light reflected by the label printing paper continuously changes within a period of time.
S108: and printing the label paper according to the printing starting position.
In the embodiments of the present specification, the controller controls the printing element to print the tab sheet according to a printing start position of the tab sheet in the tab printing sheet.
As can be seen from the method shown in fig. 3, in the present specification, light is irradiated onto label printing paper in a printer by a light source, a sensor receives reflected light reflected by the label printing paper, a photoelectric conversion circuit converts the reflected light into an electrical signal, and obtains a voltage corresponding to the reflected light, a printing start position of the label paper in the label printing paper is determined according to the voltage corresponding to the reflected light, and then the label paper is printed according to the printing start position of the label paper. In the process, the voltage corresponding to the reflected light reflected by the label printing paper is obtained through the reflection of the light, so that the printing starting position of the label paper is determined. This method of determining the printing start position by the reflection of light determines the installation of the sensor receiving the reflected light on the same side as the light source. The light source and the sensor are arranged on the same side, so that the condition that the light source and the sensor are driven by the same circuit is provided, and the possibility of reducing the cost of equipment is provided.
Further, in step S104 shown in fig. 3, the correlation between the intensity of the reflected light and the voltage output from the photoelectric conversion circuit differs depending on the photoelectric conversion circuit. Such as: the intensity of the reflected light is positively correlated with the voltage output from the photoelectric conversion circuit. That is, the stronger the intensity of the reflected light, the larger the voltage output by the photoelectric conversion circuit, and conversely, the weaker the intensity of the reflected light, the smaller the voltage output by the photoelectric conversion circuit. Corresponding to the label printing paper, the reflected light reflected by the base paper is strong, the voltage output by the photoelectric conversion circuit is large, the reflected light reflected by the label paper is weak, and the voltage output by the photoelectric conversion circuit is small.
In addition to the above-described positive correlation between the intensity of the reflected light and the voltage output from the photoelectric conversion circuit, the intensity of the reflected light may also be negatively correlated with the voltage output from the photoelectric conversion circuit, as shown in fig. 5.
Fig. 5 is a schematic diagram of a photoelectric conversion circuit provided in an embodiment of the present disclosure. In fig. 5, a photo transistor, a light emitting diode, an inverting amplifier and a plurality of resistors are included. The light emitting diode is the light source in step S100. The phototriode in fig. 5 is connected in parallel with the light emitting diode, wherein the base of the phototriode is used for receiving the reflected light reflected by the label printing paper, the collector of the phototriode is connected with the power supply, and the emitter of the phototriode is connected with the inverting input end of the inverting amplifier. The positive phase input end of the inverting amplifier is grounded, and the output end outputs voltage. The connection mode of fig. 5 can drive the photosensitive triode and the light emitting diode by using the same driving circuit. Furthermore, after the whole circuit is electrified, the light emitting diode emits light, so that the light irradiates on the label printing paper, and the phototriode receives reflected light reflected by the label printing paper. Then, the photoelectric conversion region surrounded by the dotted line converts the reflected light received by the phototransistor into an electric signal, and outputs a corresponding voltage.
As is clear from the photoelectric conversion circuit shown in fig. 5, the weaker the intensity of the reflected light, the larger the voltage output from the photoelectric conversion circuit, and conversely, the stronger the intensity of the reflected light, the smaller the voltage output from the photoelectric conversion circuit. That is, the voltage corresponding to the reflected light reflected by the label paper in the label printing paper is large, and the voltage corresponding to the reflected light reflected by the base paper is small.
Based on the above-mentioned relationship that the intensity of the reflected light is in negative correlation with the voltage output by the photoelectric conversion circuit, in step S106 shown in fig. 3, the printing start position of the label paper in the label printing paper may be determined by a method of setting a threshold value, and may include: monitoring whether the voltage corresponding to the reflected light of the label printing paper is larger than a preset threshold value or not, and determining the printing starting position of the label paper in the label printing paper according to the position of the label printing paper irradiated by the light source when the voltage corresponding to the reflected light is larger than the preset threshold value.
Specifically, the label printing paper adopts white label paper and green base paper, the voltage corresponding to the reflected light reflected by the label paper is 2.6V, and 2.6V is a preset threshold value. While the label printing paper is being transported, the controller monitors the voltage output from the photoelectric conversion circuit, as shown in fig. 6 a. In fig. 6a, a voltage within 0s to 10s is obtained, and when the time is 1.3s, the obtained voltage reaches 2.6V, and the position irradiated by the light source at the time of 1.3s is the printing start position of the label paper in the label printing paper.
Alternatively, determining a printing start position of the label paper in the label printing paper may include: and monitoring whether the voltage corresponding to the reflected light of the label printing paper is continuously increased or not, and determining the printing starting position of the label paper in the label printing paper according to the position of the label printing paper irradiated by the light source when the voltage corresponding to the reflected light is continuously increased for the preset times.
Specifically, the label printing paper adopts white label paper and green base paper, and if the preset times are 10 times. While the label printing paper is being transported, the controller monitors the voltage output from the photoelectric conversion circuit, as shown in fig. 6 b. In fig. 6b, the voltage within 0s to 10s is obtained, and 10 voltages are continuously increased within the time of 6s to 6.6s, and the position irradiated by the light source at the moment of 6.6s is the printing start position of the label paper in the label printing paper.
Further, since the label printing paper is in a state of being continuously transferred, when the controller monitors the voltage of the printing start position of the label paper, the position where the light source is irradiated on the label printing paper actually exceeds the printing start position of the label paper. Therefore, the position where the light source irradiates on the label printing paper may be determined as an initial printing start position, and then the label printing paper may be moved by a preset distance in the reverse direction of the transfer direction of the label printing paper from the initial printing start position. And determining the position of the light source irradiating on the label printing paper after the label printing paper is moved in the opposite direction as the actual printing starting position of the label paper in the label printing paper. As shown in fig. 7. The actual printing start position is the above-mentioned printing start position. The preset distance may be determined according to the transfer speed and transfer time of the label printing paper.
In fig. 7, there are label printing paper, a light source O and light emitted from the light source. At time t1, the light source O irradiates the actual printing start position of the tab sheet in the tab sheet, but when the controller of the printer monitors the voltage of the actual printing start position of the tab sheet, the position at which the light source O irradiates the tab sheet in the tab sheet at this time is time t2, that is, the initial printing start position of the tab sheet in the tab sheet. Wherein time t1 is earlier than time t 2. the distance s from the time t1 to the time t2 is a preset distance.
Based on the same idea, the present specification further provides a corresponding apparatus and a storage medium.
Fig. 8 is a schematic structural diagram of a label printing apparatus provided in an embodiment of the present specification, where the apparatus includes:
the starting module 801 is used for controlling a light source to start, so that light emitted by the light source irradiates label printing paper, wherein the label printing paper comprises label paper and base paper;
an obtaining module 802, configured to control a sensor to receive reflected light reflected by the label printing paper;
a conversion module 803, configured to control a photoelectric conversion circuit to convert the reflected light into an electrical signal, so as to obtain a voltage corresponding to the reflected light;
a determining module 804, configured to determine a printing start position of label paper in the label printing paper according to the voltage output by the photoelectric conversion circuit;
and a printing module 805, configured to control a printing element to print the label paper according to the printing start position.
Optionally, the conversion module 803 is specifically configured to, according to a preset circuit, convert the reflected light into an electrical signal, and obtain a voltage output by the circuit; wherein the lower the intensity of the reflected light, the larger the value of the voltage, and the higher the intensity of the reflected light, the smaller the value of the voltage.
Optionally, the determining module 804 is specifically configured to monitor whether the voltage corresponding to the reflected light is greater than a preset threshold, and determine a printing start position of a label paper in the label printing paper according to a position where the light source irradiates the label printing paper when the voltage corresponding to the reflected light is greater than the preset threshold;
monitoring whether the voltage corresponding to the reflected light is continuously increased or not, and determining the printing starting position of label paper in the label printing paper according to the position of the label printing paper irradiated by the light source when the voltage corresponding to the reflected light is continuously increased for a preset number of times;
determining the position of the light source irradiating the label printing paper as an initial printing starting position; moving the label printing paper to a preset distance in a direction opposite to the conveying direction of the label printing paper from the initial printing starting position; and after the label printing paper is moved in the opposite direction, the light source irradiates the position of the label printing paper, and the actual printing starting position of the label paper in the label printing paper is determined.
The present specification also provides a computer-readable storage medium storing a computer program which, when executed by a processor, is operable to perform the label printing method provided in fig. 3 above.
Of course, besides the software implementation, the present specification does not exclude other implementations, such as logic devices or a combination of software and hardware, and the like, that is, the execution subject of the following processing flow is not limited to each logic unit, and may be hardware or logic devices.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the various elements may be implemented in the same one or more software and/or hardware implementations of the present description.
As will be appreciated by one skilled in the art, embodiments of the present description may be provided as a method, system, or computer program product. Accordingly, the description may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, the description may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.
The description has been presented with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the description. It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.
These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.
In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.
The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.
