Abstract
The present invention relates to a detection device for a printer, which is mainly composed of a memory, an address counter, a time sequence coordination circuit and a reset circuit, wherein the time sequence coordination circuit is connected with a 'Busy' signal line of an interface of a printer and is connected with the interface of the printer through a data strobe signal line STB. The present invention uses a simple hardware structure to replace the detection work of a whole computer host machine for the printer, solves the problems which can not be thoroughly solved by the self-checking system of the printer, drives the printer to carry out simple printing by matching different software programs, and clearly displays the printing effects of the single pin of the printer.
Description
The present invention relates to a kind of auxiliary device of printer, be a kind of checkout equipment of printer.
In the production of printer, maintenance process, need the duty of printer be detected, at present, in testing process, need computer host system and drive the duty that printer shows printer, this is a printing control model common in the Application of Microcomputer, but under some working condition, the device resource waste that seems, and in testing process, bring many inconvenience to work.Though itself has self-checking system printer and since the design of self-checking system be with the user use and produce the debug print machine this as target, some specific detection contents can not get sufficient demonstration by the self-checking system of printer itself.As because the sample difference is printed in the printer self check, clear and definite single needle printing effect can not get sufficient demonstration, can't know the position of concrete fault pin, because self-checking system does not relate to the interface circuit of online detection, therefore the duty of the interface circuit of online detection also can not get detecting.
Purpose of the present invention is for providing printer checkout equipment a kind of easy to use, simple in structure.
The present invention adopts following measure to realize: this checkout equipment is made of storer, address counter, sequential coordination circuit and reset circuit, " Busy " signal wire of sequential coordination circuit and printer interface links, sequential coordination circuit links by data strobe signal line STB and printer interface simultaneously, send data strobe signal to printer interface, sequential coordination circuit drives address counter, and storer links to each other with the Data In-Line of printer interface.During work when printer is ready, " Busy " signal of printer interface becomes electronegative potential by noble potential, trigger sequential circuit, the requirement generation data strobe signal that it is cooperated according to sequential, make the data on the printer reception memorizer current address, printer interface is after data, " Busy " signal is become noble potential, is triggered sequential coordination circuit by electronegative potential immediately, drive address counter and add one, thereby be ready to the data that next time will transmit, when printer " Busy " signal becomes electronegative potential by noble potential again, will repeat the above course of work.
Software in the storer is to be formed according to specific print format and content compilation by printer control code and print data, according to the different software program of different needs input that detects, tests work such as machine, burn-in.
Software program among the present invention in the storer can be a kind of print routine of printer self check sample, can show the single needle printing effect of printer clearly by this self check sample.
The present invention has substituted the testing of whole main frame to printer with simple hardware construction, solved the problem that the printer self-checking system can not fully solve simultaneously, and be equipped with different software programs, can drive printer and carry out simple print job, as print simple ticket card etc.This checkout equipment also is simple in structure and convenient in use.
Description of drawings:
Accompanying drawing Fig. 1 is the signal of detecting device internal circuit configuration;
Accompanying drawing Fig. 2 is the specific self check sample of detecting device;
In conjunction with the accompanying drawings the present invention is further described as follows, checkout equipment of the present invention is by storer (ROM), address counter, sequential coordination circuit and reset circuit constitute, " Busy " signal wire and the sequential coordination circuit of printer interface link, sequential coordination circuit links by data choosing energy signal wire STB and printer interface simultaneously, send data strobe signal to printer interface, sequential coordination circuit drives address counter, address counter links to each other with storer (ROM) by address wire, storer links to each other with the Data In-Line of printer interface, and on storer (ROM), there is a print routine of specific printing sample, reset circuit at first places suitable original state to the address counter O reset and with sequential coordination circuit during work, when printer is ready, printer " Busy " signal becomes electronegative potential by noble potential, trigger sequential circuit, make it send data strobe signal according to the requirement that sequential cooperates, make the data on the printer reception memorizer current address, carry out the print routine of specific printing sample, printer interface " Busy " signal after data becomes noble potential by electronegative potential immediately, sequential coordination circuit driving this moment address counter adds one, thereby the data that are ready to store on the next address, for the transmission of data is next time got ready, when printer " Busy " signal becomes electronegative potential by noble potential again, the above course of work will be repeated, carry out the print routine of specific printing sample, can obviously demonstrate the single needle printing effect of printer from this specific printing sample, thereby accurately find the position of fault pin.If there is the print routine of other content in the storer (ROM), printer can carry out other simple print job under the driving of this detecting device.If printer is cisco unity malfunction under the driving of detecting device, cooperate the self-checking function of printer can determine whether the interface circuit of printer has fault.
