Printing method capable of reducing cost

Abstract

The invention relates to the field of printers, in particular to a printing method capable of reducing cost, which is characterized by comprising the following control processes of: 1, carrying out initializing; reading font dot matrix data of various pre-stored characters, and querying list information data; finishing initialization, transmitting the data to the MCU, and temporarily storing the data in a data annular buffer area opened up in the MCU; 2, carrying out pre-analysis; detecting and acquiring data in the data annular buffer area, and extracting the data to be temporarily stored inthe memory container; step 3, carrying out printing; obtaining data entries temporarily stored in a memory container, and drawing the data entries into a graph in a dynamic scanning area of the dynamic scanning block; and sending the drawn graph to a printing unit, and enabling the printing unit to scan and print the graph; 4, repeating the processes of the step 2 and the step 3 until all graphs analyzed from the entry data are printed; and 5, finishing printing. According to the printing method provided by the invention, the hardware cost is reduced, and the utilization rate of the memory isimproved.

Description

technical field [0001] The invention relates to the field of printers, in particular to a printing method with reduced cost. Background technique [0002] Thermal printer is a technology based on heating algorithm to realize imaging on thermal paper. Usually, the body size is small and the price is relatively low. In the early days, it was mainly used in the printing of shopping list vouchers in shopping malls and supermarkets. With the rapid development of logistics express, thermal printers are widely used in the express logistics industry, and the main application scenario is to print express orders. Due to the express train of logistics and express delivery, the dedicated thermal printers have grown exponentially. All major printer manufacturers have heard the news and have increased their investment in the research and development and production of thermal printers. Now, basically the printers produced by various manufacturers have no big difference in function and te...

Problems solved by technology

This has a disadvantage, which limits the efficiency of memory usage. Before the printing is completed, the drawn RAM area is actually occupied all the time, that is, a printing task can only be used once, and it also limits the graphics page in the application. size, it is required that the page area to be printed cannot exceed the physical memory area of ​​the actual RAM, and the purchase of plug-ins increases the cost of hardware
