Printing driving method and printing driving device of a POS machine

Abstract

The invention belongs to the technical field of printing driving, and provides a printing driving method and a printing driving device of a POS machine. In the printing driving method of the POS machine, the POS machine comprises a printing module; a heating module in the printing module consists of multiple sections of identical heating bodies; a printing instruction is received; a power supply signal of a power supply of the POS machine is obtained according to the printing instruction; the power supply is judged as an accumulator according to the power supply signal; if so, the multiple sections of heating bodies are controlled to respectively perform heating and printing according to printing and heating sequences; and if not, the multiple sections of heating bodies are controlled to synchronously perform heating and printing. When the power supply of the POS machine is the accumulator, the multiple sections of heating bodies can be controlled to respectively perform heating and printing according to the printing and heating sequences, so that the phenomenon of stopping supplying power to the POS machine due to triggering of an automatic protection mode caused by higher instantaneous current of the POS machine is prevented, and the continuous printing stability of a printing module in the POS machine is improved.

Description

technical field [0001] The invention relates to the technical field of print driving, in particular to a print driving method and a print driving device of a POS machine. Background technique [0002] With the increasing popularity of the e-commerce industry and smart payment, merchants' demand for multifunctional POS machines (Point of sales) is also increasing. For example, when delivering goods to e-commerce customers, it is necessary to swipe the card through the POS machine. For another example, when performing smart payment through an APP application (Application, application program) on a mobile terminal, a POS machine is still required to scan and pay. After using the POS machine to carry out commodity transactions, the POS machine prints out transaction vouchers or lists, etc. through its internal printing module. But, because the printing module that is used to print voucher or checklist in the existing POS machine is powered by the battery of the POS machine, th...
