Report printing method and device for a thermal printer

Abstract

The invention relates to the field of printers and in particular relates to a report printing method and a report printing device of a thermal printer. The method comprises preprocessing collected electrocardiosignals to obtain the waveform data of a waveform position within a longitudinal print area, and converting the processed waveform data into an ECG data waveform needed by longitudinal printing, thereby realizing the longitudinal printing of an ECG waveform report. According to the report printing method and the report printing device of the thermal printer, the problem of failure in effectively avoiding waveform overlapping between leads even though the gain is adjusted to the minimum value due to the layout of transverse type setting during transverse printing is solved, and meanwhile, due to longitudinal printing, the analyzability, the readability and the beauty of the waveform of the ECG report are further improved.

Description

technical field [0001] The invention relates to the field of printers, in particular to a report printing method and device for a thermal printer. Background technique [0002] The working principle of the thermal printer is to send the data received by the thermal printer to the thermal heating unit through the shift register inside the thermal printer, and the thermal heating unit will transfer the data on the corresponding thermal paper according to the received data The heat-sensitive coating is heated. At present, thermal printers have been widely used in POS machines, banking systems, medical equipment such as electrocardiogram machines, monitors, etc. Because thermal printers have the advantages of low noise, fast speed, high reliability, clear printing characters, and miniaturization, they have also been widely used in the field of medical instruments, mainly in electrocardiographs, monitors, and inspection instruments. Print test data, waveforms, etc. [0003] As...

AI Technical Summary

Problems solved by technology

Generally, ordinary printing paper adopts the A4 paper specification with an aspect ratio of 4:3. When the number of printed leads is too many, especially when it reaches 12 or more leads, the horizontal typesetting will appear to have too small waveform spacing, which often The overlapping of waveforms between different leads causes the printed waveform spacing range to be insufficient to represent the details of the complete ECG waveform (such as Figure 7 )

In order to solve this problem, users usually can only adjust the printing gain of the waveform to ensure that the details of the waveform are not covered by the waveform content of other leads, and this method will reduce the amplitude of the printed waveform, resulting in many details that cannot be clearly presented. Reduces the readability and analyzability of the lead waveform; when the number of leads reaches 16 leads and above, the layout of the horizontal layout cannot effectively avoid the waveforms between the leads even if the gain is adjusted to the minimum value. overlap, while also seriously affecting the waveform analyzability, readability, and aesthetics of the ECG report
