Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described in detail.
As shown in Figure 1, be the know-why schematic diagram of a kind of Embedded Relay Protector print control program provided by the invention, the central inventive point of the method is not revise executable target program.
As shown in Figures 2 and 3, first, the printing script engine being used for performance objective program is set in Embedded Relay Protector and several are set and print script file.Wherein, the business printing script file and embedded equipment is one to one, and one prints the corresponding a kind of business of script file.When embedded equipment is under some business, the printing script file in device is corresponding with this business.Changing the step printing script file is: first unload original printing script file, then download new printing script file, specifically see step 2 below.
Arranging the concrete steps printing script file is:
1, print the structure of script file: first determine the printing script file needing to arrange according to the business module of device, then generated by script the build tool or the manual create-rule according to printing script file and print script file;
2, download and the unloading of script file is printed: download in embedded equipment by specific download instrument by printing script file, also by download tool, the printing script file in device is deleted, thus realize the unloading printing script file, the printing function of the corresponding business of this script file is unloaded with this.
Arrange to print while script file, before or complete time, need to arrange printing outlet terminal.By setting of printing menu setecting, printout terminal device (printer or file) is set, be specially: under supporting document exports printing operating mode, setting of printing menu is selected first to be presented on interface by printout terminal name (printer or file), and choose on the terminal name item preserved last time in advance, the reconfigurable new outlet terminal index of user is also preserved, and all business printouts of system will synchronously proceed to the terminal of relative set.When select with printer be terminal carry out printout time, carry out printing by the printer selected; When select with file be terminal carry out printout time, send backstage by file service by printout.After arranging the success of outlet terminal equipment, script engine (or being referred to as print engine) will enter environment corresponding to printout terminal immediately, and this arranges the characteristic that printout terminal has power down maintenance.
