Abstract

PURPOSE:To print out data whose reduction/enlargement is unnecessary in unmagnification state and to print out data other than the above while subjecting it to variable magnification of required magnification by executing variable magnification processing(VMP) to other data without applying VMP only to data specified by a data specifying means. CONSTITUTION:Prior to printing, a user sets up, for instance, a reduction rate and a reduction mode respectively to 80% and a fixed resolution mode by operating a panel device 110 and sends data in a 80% variable magnification reduction mode. Data from a host device 112 are read out, and since the initial data are character data, the existence of variable magnification reduction is confirmed and characters are stored in a page buffer after executing the variable magnification processing of 80/100 multiplication. Succeeding data are ruled line data, which are stored after being subjected to similar variable magnification processing since data succeeding the above are an unmagnification setting command, variable magnification processing is not executed to this and succeeding data. Since a bar code printing command is sent thereafter, the command is stored at it is without executing variable magnification processing. After releasing unmagnification, the contents of a page concerned are printed out by a page paper discharging command.

First, a first embodiment of the present invention will be described. Here, a case will be described in which a slip containing barcode data is reduced and printed. The print data sent from the host device 112 is composed of character data, ruled line data, equal size setting command, and bar code data, as shown in FIG. In this embodiment, before printing, the user operates the panel device 110 to set the reduction ratio to 80% and the reduction mode to the fixed resolution mode.
The data shown in FIG. 2 is sent in the 80% scaling mode. Then, the data sent from the host device 112 is read. Initially, since it is character data, it is confirmed that the reduction mode is scaling reduction, and the character is scaled by 80/100 and stored in the page buffer.

Next, since the read data is ruled line data, it is also subjected to the same scaling processing and stored in the page buffer. Since the next data is the same-magnification setting command, it is stored that the data subsequent thereto is not subjected to the scaling process. After that, since a bar code print command is sent, this data is stored in the page buffer as is without being subjected to scaling processing. Then, the normal size is released and the page is printed by the page discharge command. As a result, it is possible to obtain a print result as shown in FIG. In this embodiment, the entire page is subjected to the scaling process, whereas only the designated data portion is printed at the same size. Therefore, there is no bit omission or rattling accompanying the scaling process. Further, since the print data can be designated, editing can be easily performed even if the print position is changed.

Next, the second embodiment will be described. First, as in the first embodiment, the 80% scaling mode is set. Then, the data of FIG. 3 is sent. Among the sent data, the character code and the ruled line code are processed in the same manner as in the first embodiment. The next data sets the equal size area. In this area, the area for printing the barcode of FIG. 4 is designated. After that, when the bar code data is printed in the area, the data in the set area is stored in the page buffer without being scaled, as is. If other data such as characters is printed in this area, the data is also printed at the same size without performing the scaling process.

After that, the page is printed by the page discharge command. As a result, it is possible to obtain a print result as shown in FIG.
In this embodiment, the scaling process is performed on the entire page, whereas the designated area is printed at the same size. Therefore, there is no bit omission or rattling accompanying the scaling process. Further, since the print area can be designated, the same size processing can be performed on any data without depending on the type of data.

Next, a third embodiment will be described.
First, before printing, the user operates the panel device 110 to set the reduction ratio to 80%, the reduction mode to the variable resolution, and the 80% variable resolution reduction mode. And
The data shown in FIG. 2 is transmitted. First, the host device 112
Read the data sent from. Since it is the variable resolution mode, the reduction ratio is set by changing the resolution of the engine 108. The engine resolution for 100% reduction (actual size) is 240 dpi, so here, 240 dpi ÷ 80
% = 300 dpi is set. Since the first data is character data, the character is directly expanded in the page buffer. Since the next read data is ruled line data,
This is also expanded in the page buffer as it is.

Since the next data is the same-magnification setting command, the enlarging / magnifying processing is performed on the subsequent data.
Then, when the barcode print command is sent, the barcode portion is subjected to 100/80 times magnification / magnification processing and stored in the page buffer. At this time, the scaling processing is performed only on the barcode portion as shown in FIG. As a result, it is possible to obtain a print result as shown in FIG. In this embodiment, the designated data is subjected to a scaling process, but the entire page is printed by changing the engine resolution, so that the page development time is short. Further, since the print data can be specified, editing can be easily performed even if the print position is changed.

Then, a fourth embodiment will be described.
Similar to the third embodiment, the 80% variable resolution reduction mode is set. Then, the data of FIG. 3 is sent. After that, as in the third embodiment, 300 dpi is applied to the engine 108.
The resolution is set, and the character code and the ruled line code in the sent data are processed in the same manner as in the third embodiment. The next data sets the equal size area. In this area, the area for printing the barcode of FIG. 6 is designated. After that, when the bar code data is printed in the area, the data in the set area is subjected to 100/80 times magnification / magnification processing and stored in the page buffer. If other data such as characters is printed in this area, the data is also subjected to enlargement / magnification processing, and as a result, it is printed at the same size.

After that, the page is printed by the page discharge command. Then, as shown in FIG. 7, a print result is obtained in which only the bar code portion is scaled.
In this embodiment, the specified area is subjected to the scaling processing, but the entire page is printed by changing the engine resolution, so that the page expansion time can be shortened. Further, since the print position can be specified, the same size processing can be performed on any data regardless of the type of data.

The processing procedure of the first to fourth embodiments will be described with reference to the flowchart of FIG. First, the reduction mode is set (step 1). Then, the data is read (step 2). Then, it is judged whether or not this printer device is set to the reduction mode (step 3). When the reduction mode is not set, that is, when the magnification is 100% (step 3; N), normal printing processing is performed (step 4), and the processing returns to step 2 and continues.

On the other hand, when the reduction mode is set (step 3; Y), it is judged whether or not the variable resolution is reduced (step 5). Then, when the variable resolution reduction is selected (step 5; Y), it is determined whether or not the data is equal-sized data (for example, data such as a bar code that does not make sense when reduced) (step 6). ).

When the data is equal-sized data (step 6; Y), the enlargement / reduction processing of the equal-sized data is performed (step 7). If the data is not the same size data (step 6; N), the scaling process is not performed. Also, when the variable resolution mode is not set, that is, in the scaling reduction mode (step 6; N), it is determined whether the data is equal size data (step 8), and if the data is equal size data (step 8). Y), the scaling process is not performed, and when the data is not the same size data (step 8; N), the normal scaling process is performed (step 9). Then, when all the print data have been completed (step 10; Y), the processing is ended, and when not completed (step 10; N), the step 2 return processing is continued.
