[0037] Reference is made to Figure 1 , Figure 1 is a flowchart of a method for implementing printing of any resolution provided by an embodiment of the application. Through the method, printing of any resolution can be implemented, as shown in Figure 1 The method comprises the following steps S1-S5.

[0038] S1, generating a periodic reference signal based on the scale of a measuring instrument.

[0039] In a specific implementation, the measuring instrument comprises an optical grating and a magnetic grating. Those skilled in the art can use an optical grating or a magnetic grating as a measuring instrument according to actual conditions, and the application does not specifically limit this.

[0040] Specifically, a decoder generates a periodic reference signal based on the scale of the measuring instrument, and each scale corresponds to a period of the reference signal. The reference signal has a rising edge and a falling edge.

[0041] S2, obtaining a target resolution, and determining the ratio of an inkjet period to the signal period of the reference signal based on the target resolution and the reference resolution of the measuring instrument.

[0042] In a specific implementation, the target resolution is the resolution set by the user. It can be understood that the target resolution can be set by the user arbitrarily, and the present application does not make specific limitations.

[0043] The reference resolution of the measuring instrument is a parameter of the measuring instrument and is fixed. For example, in an embodiment, the reference resolution of the measuring instrument is 180 dpi.

[0044] Specifically, the ratio of the inkjet period to the signal period of the reference signal is determined based on the target resolution and the reference resolution of the measuring instrument, and specifically, how many raster (magnetic raster) points (one raster (magnetic raster) point corresponds to one scale) correspond to each image point (inkjet point) is calculated.

[0045] In an embodiment, the above step of "determining the ratio of the inkjet period to the signal period of the reference signal based on the target resolution and the reference resolution of the measuring instrument" specifically includes: obtaining the quotient of the reciprocal of the target resolution and the reciprocal of the reference resolution as the ratio.

[0046] In a specific embodiment, the resolution of the raster is 180 dpi, and when an image with a target resolution of 310 dpi needs to be printed, then each image point = (1 / 310) / (1 / 180) = 0.5806 raster points, that is, an image point is printed every 0.5806 raster periods. Therefore, the ratio of the inkjet period to the signal period of the reference signal is 0.5806.

[0047] S3, obtaining the time length of the signal period of the reference signal.

[0048] In a specific implementation, the time length of the signal period of the reference signal is measured in real time.

[0049] For example, in an embodiment, the above step of "obtaining the time length of the signal period of the reference signal" specifically includes: starting counting from the rising edge / falling edge of the reference signal at a preset reference frequency, stopping counting until the next rising edge / falling edge of the reference signal, and obtaining a count value; determining the time length of the signal period of the reference signal based on the count value and the reference frequency.

[0050] Specifically, the fpga (Field-Programmable Gate Array, Field-Programmable Gate Array) program of the printer starts counting from the rising edge of the reference signal at a reference frequency of 70 Mhz, stops counting until the next rising edge, and obtains a count value. The count value divided by the reference frequency is the time length of the signal period of the reference signal.

[0051] Or, counting from the falling edge of the reference signal to the next falling edge with a reference frequency of 70Mhz, a count value is obtained. The count value divided by the reference frequency is the length of the signal period of the reference signal.

[0052] Or, counting from the rising edge of the reference signal to the next falling edge with a reference frequency of 70Mhz, a count value is obtained (only half a period is counted). The count value divided by the reference frequency multiplied by 2 is the length of the signal period of the reference signal.

[0053] Or, counting from the falling edge of the reference signal to the next rising edge with a reference frequency of 70Mhz, a count value is obtained (only half a period is counted). The count value divided by the reference frequency multiplied by 2 is the length of the signal period of the reference signal.

[0054] S4, determining the inkjet period based on the length of the signal period and the ratio.

[0055] In specific implementation, the length of the inkjet period can be determined according to the length of the signal period and the ratio.

[0056] For example, in an embodiment, the step of “determining the inkjet period based on the length of the signal period and the ratio” specifically includes: obtaining the product of the length of the signal period and the ratio as the inkjet period.

[0057] S5, determining a starting point from the reference signal, and based on the inkjet period, controlling the printer to repeatedly perform inkjet starting from the starting point.

[0058] In specific implementation, a starting point of starting printing is determined from the reference signal, and then based on the inkjet period, the printer is controlled to repeatedly perform inkjet starting from the starting point, i.e. one inkjet point is printed every inkjet period. See Figure 2 The rising edge of the reference signal is taken as the starting point of starting printing, and each landing point (inkjet point) of the printer is determined, and printing is performed once at each landing point.

[0059] In an embodiment, the step of “determining a starting point from the reference signal” specifically includes: taking the rising edge / falling edge of the reference signal as the starting point. That is, the rising edge or the falling edge of the reference signal can be taken as the starting point of starting printing, which is not specifically limited by the present application.

[0060] In an embodiment, the step of "controlling the printer to repeatedly perform ink ejection based on the ink ejection period from the starting point" specifically comprises: controlling the printer to start ink ejection from the starting point, and then controlling the printer to perform ink ejection once, i.e. print one ink ejection dot, every time an ink ejection period elapses.

[0061] After that, each time a print job is started, the target resolution input by the user is received, the steps S1-S4 are repeated to determine the ink ejection period, the ink ejection period is sent to the fpga program of the printer, and then the step S5 is performed to realize printing at any resolution.

[0062] The technical scheme of the embodiment of the present application generates a periodic reference signal based on the scale of a measuring instrument; acquires a target resolution, determines the ratio of the ink ejection period to the signal period of the reference signal based on the target resolution and the reference resolution of the measuring instrument; acquires the time length of the signal period of the reference signal; determines the ink ejection period based on the time length of the signal period and the ratio; determines a starting point from the reference signal, and controls the printer to repeatedly perform ink ejection based on the ink ejection period from the starting point, so that printing at any resolution can be realized, and the applicability is wider. Moreover, the present scheme can be realized based on the original raster or magnetic raster of the printer, without the need to replace the raster or magnetic raster, and the cost is lower.
