Although the printer model computer software occurred discerning automatically, do not occur a kind of printer parameter being provided with computer settings, and the software solution of the bidirectional data transfers of feedback feedback printer parameter.
Summary of the invention
The object of the present invention is to provide a solution and realization, by setting and the feedback of software mode realization to printer parameter, especially a kind of software solution of bidirectional data transfers is used for the setting to printer parameter.Software mode adopts computer operation to replace the printer button operation, has human-computer interaction interface attractive in appearance, and easy mode of operation has been saved the running time, has improved work efficiency, has also saved paper simultaneously, has reduced noise, more environmental protection.
In order to achieve the above object, the present invention is realized by following technical scheme.
Method for online set of printer parameter is the basis according to automatic identification printer model computer software, with setting and the feedback of software mode realization to printer parameter.Comprise and be provided with the automatic recognition software that runs on computing machine, the software that runs on printer, based on the two-way communication between printer and computer parallel port, the software that uses a computer is discerned on the basis of printer model automatically, and pack into the menu of simulation type coupling, set printer parameter, obtain Printer Information, the control printer carries out special operational, and finish line feed, skip, function of initializing.
Improvement of the present invention comprises: the multiplexing control of parameter is set, and after primary parameter is set exactly and preserves, can be with the parameter quick copy that is provided with to other homotype printer.
The inventive method constitutes application software system, form by the special printer program that runs on the computer application program and run on printer that (system architecture is referring to accompanying drawing 1, express for convenient, hereinafter will run on the computer application program and abbreviate " PA " as, printer program be abbreviated as " PR ").
The software systems that this invention constitutes are characterised in that:
PA is based on the window class application program of WINDOWS operating system exploitation, and title is " the online setting of DPK printer ", is furnished with special-purpose installation procedure.PA comprises menu bar, toolbar, user area for the user provides visual graphical interfaces (referring to accompanying drawing 2), and the user uses that mouse is selected, change, preview and preservation printer parameter.PA is responsible for printer parameter and other operation that the user is provided with are sent to printer as request, can obtain printer parameter and is shown in the graphical interfaces by the parallel interface (hereinafter referred " parallel port ") of computing machine.PR is special DPK printer software, remove and finish general printing function, can also respond the request of PA, response has 3 classes: carry out the request of the request that parameter is set, the request of carrying out the control printer and execution feedback printer data, feedback sends to computing machine through the printer parallel port.
PA adopts database to store and obtain the menu information (menu item, candidate parameter) of printer.PA when operation, from database, obtain the menu information of this type by the printer model of current setting, with the printer parameter data combination of obtaining, generate the user area content from the parallel port.These contents can also be upgraded automatically according to user's operation.
PA adopts the parallel port to receive the feedback of PR.IEEE 1284 communication protocols of following PA realize the reverse data transmission control of parallel port.Described oppositely index is according to sending to computing machine by computer peripheral, and is opposite with data transfer direction under the normal operating mode of parallel port.
PA sends to the request of printer, is the data that meet expansion emulation command form, and the machine parallel port sends to printer as calculated, and the parallel port is a normal operating mode.Described expansion emulation command refers to disjoint, the custom-designed command set of this software of emulation command collection with the printer support.
