The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is done and to further describe.
As shown in Figure 2; The present invention provides a kind of general printing drive module; The various impact printers that the operation principle difference is very big drive unified integration with thermal printer and become a cover to drive, and specifically comprise and print API module, character pattern parsing module and movement driver module, it is characterized in that: described printing API module (Print API Modules; PAM) application programming interfaces with the particular hardware platform independence are provided, its major function is that lower floor's device driver is encapsulated.It drives the printing API that the function that provides is packaged into various realization concrete functions with character pattern parsing driving and movement, for example: character printing, image printing, paper feed etc. according to the demand of application program.
(Dot Convert Modules DCM), can be divided into 3 sub-module to described character pattern parsing module: get the character pattern submodule, realize obtaining from holder according to the input character ISN dot matrix of this character; Dot matrix gyrator module realizes the dot matrix spinfunction, can support 90 degree, 180 degree and 270 degree dot matrix rotations; Dot matrix expansion submodule is realized the dot matrix enlarging function, can support multiple times wide, high, wide times of high font doubly doubly.This character pattern parsing module is with printing and paper feed operation, and (General Dot Unit GDU), offers the movement driver module and uses to convert general dot-matrix information unit into.Described general dot-matrix information unit form:
Dot matrix number (DotNum): represent the dot matrix number that this row need be printed; Dot array data (DotData): the dot matrix content of representing this line printing; Paper feed amount (Steps): represent the paper feed step number that this line printing is intact.
(DotData is any for General FeedDot Unit, GFDU) form: DotNum=0, Steps=paper feed amount for universal some array element of paper feed operation (Feed);
(General PrintDot Unit, GPDU) form: DotNum=N, DotData are the dot matrix content to universal some array element of printing (Print), Steps=paper feed amount.
After general dot-matrix information unit GDU formed, described character pattern parsing module can merge continuous GFDU, and adjacent GPDU and GFDU merge.Therefore the various paper feeds and the printing of print procedure converts a minimum GDU tabulation of item number at last to, offers the movement driver module again.
