Abstract

PURPOSE:To process received data in a single analyzing action as long as no received data exists within a printer device and the next print data can be compiled, by adding a 3rd analyzing part to an interface part to analyze the received data. CONSTITUTION:When a printer contains no received data, the received data are fetched via an interface part 12 and analyzed by the 3rd analyzing part 1. At the same time, the interface signal which is transmitted in response to the result of analysis is changed. These analyzed data are shown by deforming the received data with the analysis information and sent to a compiling part 16 together with the internal processing data to be printed at a printing part 17. In such a manner, those data can be printed just through a single analyzing action since the processing is carried out in a route (c). While the processing route is switched to a route (a) if the printer contains the received data and these data are temporarily stored in a reception buffer 14 after the analysis is finished at the part 13. Then the processing is set in a route (b) and those data are processed when the printing job is finished at the part 17.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer device, and particularly relates to data analysis processing in the printer device.

[Conventional technology]

In general, printer devices are configured to include an analysis section that checks whether input data conforms to the format of a control code, thereby effectively performing internal processing. That is, when certain data is received, it is checked whether there is a control code corresponding to the data, and if there is, it is processed as is, but if there is not, the data is discarded.

FIG. 2 shows a block diagram showing the internal processing of a conventional printer of this type. In FIG. 2, an interface unit 12 is provided to perform mutual interface processing between a host side device (not shown) and a printer device. A first analysis section 13 performs a predetermined analysis on the received data taken in through the interface section 12. At this time, the first analysis section 13 changes the interface signal sent from the first analysis section 13 to the host-side device connected to the outside via the interface section 12 immediately after receiving it. In some cases, a function for notifying the status of the printer device is performed at the same time. For example, in the case of "rDC3 code", when it is determined as a DC3 code as a result of analysis, the interface signal rsELEcTJ is changed at that point.

Thereafter, the received data is stored in the -H reception buffer 14 as is.

Next, the data retrieved from the reception buffer 14 via the editing section 16 is analyzed again in the second analysis section 15, then edited in the editing section 16, and then sent to the printing section 17 for printing processing. is configured to do so.

[Problem that the invention seeks to solve]

In conventional printer devices, when storing received data in the reception buffer 14, the first analysis section 13 performs analysis processing, and after reading the data from the reception buffer 14, the second analysis section performs editing for editing. analysis processing to be performed.

As described above, in conventional printer devices, one piece of data must always be analyzed twice, so there is a problem in that the processing speed cannot be improved.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a printer device that improves the disadvantages of the prior art and significantly improves the processing speed of received signals.

[Means for solving problems]

In the present invention, the data received by the interface section is
In a printer device that analyzes the data by a second analysis unit, stores it once in a reception bar sofa, analyzes the stored data again by a second analysis unit, performs editing processing, and prints the data, the received data is sent to the interface unit. We have newly equipped a third analysis section for analysis. When there is no data being edited in the printer device, the third analysis section analyzes the received data and immediately performs the editing process.

[Embodiments of the invention]

FIG. 1 is a block diagram showing internal processing of a printer showing an embodiment of the present invention. Here, the same reference numerals are used for the same components as in the conventional example described above.

In FIG. 1, if there is no received data inside the printer, the received data is processed through the path shown in C. That is, the received data taken in through the interface section 12 is analyzed in the third analysis section 1, and at the same time, the interface signal sent out from the interface section 12 is changed according to the analysis result. The analyzed data is sent to the editing unit 16 together with analysis information, i.e., internal processing data that is data that is made easier to edit by transforming the received data to represent which function is specified by the control code. sent to. The editing section 16 performs editing processing on these data, and then sends the processed data to the printing section 17, whereupon printing processing is performed in the printing section 17.

In this way, if there is no received data inside the printer, processing is performed through route C, so that printing can be performed by analyzing the received data only once.

When the printer device is in a printing state and the next editing process cannot be performed until printing is finished, that is, if there is data that has already been received inside the printer device, the internal processing is performed using the route shown in a. Switch to As a result, the first analysis section 3 analyzes the received data taken in through the interface section 12, and the first analysis section 3
After performing processing to change the interface signal sent from the terminal, the received data is stored in the -H reception buffer 14 as is.

When the printing process in the printing unit 17 is completed and the state is ready for editing the next print data, the internal processing path is switched to b and the data received up to that point is processed. That is, the data taken out from the reception buffer 14 via the editing section 16 is analyzed again in the second analysis section, and then sent to the editing section 16 together with the analysis information. Editorial department 1
Editing processing is performed in step 6, and the edited data is sent to a printing unit 17 where printing processing is performed.

If the receiving buffer runs out of data while editing is being performed, the internal processing path is switched to C again at that point.

In this way, in the above printer device, if there is no received data inside the printer device and it is possible to edit the data to be printed next, when the data is received, -degree analysis is performed. The internal data processing for printing can be completed just by doing this.

〔Effect of the invention〕

As explained above, according to the present invention, when there is no received data inside the printer device and the next print data can be edited, the received data can be processed with only one analysis, so it is always possible to process the received data twice. This has the effect of shortening the processing time compared to conventional printer devices that require analysis.
