Equipment with printing drive function and method for implementing printing drive

Abstract

The invention provides equipment with a printing drive function and a method used for achieving the printing drive; the equipment comprises a multi-core CPU chip which can achieve at least two-core function; wherein, one core is a main control CPU0 which is used for main control of the equipment and the other core is a driving CPU1 which is connected with a printing drive circuit and used for controlling the printing of a recorder; the CPU0 transmits downstream data to the driving CPU1 by sharing memory; the CPU1 transmits the upstream data to the CPU0 by sharing memory; the CPU0 and the CPU1 achieve the communication by sharing memory. The equipment and the method can improve the printing speed and performance, reduce the cost and are a simple realization type for the recorder driving circuit with high efficiency and low cost.

Description

technical field [0001] The invention relates to recorder driving technology, in particular to a device with printing driving function and a method for realizing printing driving. Background technique [0002] Thermal printing is mostly used for bill printing in bank self-service terminals, supermarkets, etc., and for printing test results in medical electronic products. Among these products: some products have strict requirements on printing real-time and printing speed accuracy, such as the printing of ECG (cardiac electricity) waveforms on monitoring devices and electrocardiographs in medical products, which require uniform speed printing (there are two speeds of 25mm / s and 50mm / s), the speed accuracy is required to be within ±5%; some products require high-speed printing, such as bank self-service terminals and ticket printing in supermarkets. In order to reduce customer queuing time, the printing speed should be as fast as possible. Therefore It can be seen that there a...

Problems solved by technology

And to achieve a higher printing speed, the data transmission process must be very complicated

Therefore, the disadvantages of method (1) are: the hardware of the system is complicated, the communication protocol is complicated, the processing process is complicated, the overhead of the upper computer and the lower computer software is large, and the cost is high

[0005] (1) A system using two CPUs: complex hardware, high cost, complex communication protocol, and high software overhead;

[0006] (2) A system using a single CPU: the CPU has to handle multiple tasks, and it is difficult to guarantee the real-time printing
