Portable intelligent barcode machine

1. Title of Invention : Patent Number for Portable Intelligent Barcode All-in-One. 1
Abstract: This utility model is a portable intelligent barcode integrated machine, which relates to the field of printing equipment. It solves the technical shortcomings of the original bar coder that must be connected to the computer. The design principle is to use the embedded computer technology to design the computer and thermal transfer/thermal printer control board as a whole. The hardware of the core control system adopts single-chip CPU, R0M, RAM, and clock chip, which are connected through the data address bus, and R0M at the same time. Built-in monitoring program: Machine initialization program, keyboard monitoring program, LCD display program, printing program, font library program. The core control system uses bus extensions to connect chips such as the EPM7128, 74LS245, A3952, and the detection signal interface to form a mainboard system. The mainboard is connected to external devices such as printheads, stepper motors, keyboards, liquid crystal displays, detection tubes, and paper cutting motors, and monitors the peripherals by programs. The portable smart barcode all-in-one machine will be used for mobile jobs with bar code label printing.
