Embodiment

[0026] In this embodiment, only one hardware timer is used to realize the method for driving a thermal printer, the method is implemented based on an interrupt processing program installed in the hardware timer, and the hardware timer is respectively connected to the paper feed motor and the heating head;

[0027] The interrupt processing program is specifically implemented according to the following steps: when printing each new dot line data, calculate the heating time T and the phase change time t of the paper feed motor required to print the new dot line, and at the same time, obtain the phase change of the paper feed motor time t 0 , from t 0 Start to split the overall time required to print a new dot row into two time periods: the phase change time t of the paper feed motor and the heating time T; from t 0 At the beginning, drive the paper feed motor to the specified position, and the time period for the paper feed motor to travel is less than or equal to t; from the he...

Abstract

The invention discloses a method of using only one hardware timer to realize thermosensitive printer driving and relates to the POS machine equipment driving program field. The method is realized based on an interruption processing program installed in the hardware timer. The hardware timer is connected to a paper feed motor and a heating head. The interruption processing program is characterized by when each new point row data is printed, calculating heating time T needed by new point row printing and paper feed motor phase change time t, and simultaneously, acquiring paper feed motor phase change time t0, splitting integral time needed by new point row printing into two time periods of the paper feed motor phase change time t and the heating time T from the t0; from the t0, driving a paper feed motor row to an assigned position, wherein the paper feed motor row walking time period is less than or equal to the t; from a heating time head T0, starting a heating head, loading new point row data and printing the data; and when printing is ended, closing the heating head and then closing the hardware timer. A utilization rate of a space is increased and system performance is increased too.

Description

technical field [0001] The invention relates to the field of POS device driver programs, in particular to a method for realizing thermal printer driving by using only one hardware timer. Background technique [0002] The existing POS machine system needs multiple hardware timers to realize the printing function during the printing process. Among them, the traditional thermal printer installed on the POS machine needs at least two hardware timers, one is used to control the paper feeding motor, and the other is used to control the heating time. The increase in the number of hardware timers takes up the internal space of the POS machine, and increases the The volume of the machine. Contents of the invention [0003] The purpose of the present invention is to provide a method for driving a thermal printer using only one hardware timer, so as to solve the aforementioned problems in the prior art. [0004] In order to achieve the above object, only one hardware timer is used ...
