FIG. 1 shows an embodiment of a data output device according to the present invention. In FIG. 1, reference numeral 1 denotes a pattern signal (dot) based on print data (for example, a character code) input from an external device such as a host. And a pattern generator for generating a pattern), which is composed of a well-known character generator, a page memory, and the like. Reference numeral 2 denotes an output device such as a laser beam printer for recording an image on a cut sheet based on a pattern signal output from the pattern generation device, and 3 changes the interval or size of the dot pattern output from the pattern generation device 1. Therefore, the data changing device 4 that sends the size change data to the pattern generating device 1 performs a predetermined calculation according to the form of the sheet used in the output device 2 and outputs the calculation result to the data changing device 3.
This is a ratio calculation device for sending to a user.

The print data input to the circuit of FIG. 1 is originally designed for continuous paper, but according to the present embodiment, the input print data is changed to cut paper, and As described above, image recording is performed in such a manner that the first line of the continuous paper coincides with the first line of the cut paper so that the cut paper is not unsightly.

As an initial stage, the ratio calculation device 3 calculates a ratio α between the vertical length B of the cut paper used in the output device 2 and the vertical length b of the continuous paper on which the input print data is to be originally printed.
To It is calculated by: Then, the calculation result based on the expression is sent to the data changing device 3. When the print data is input to the pattern generation device 1, for example, information related to pitch (eg, vertical tab, page length setting command, etc.) is multiplied by α by the data change device 3 and passed to the pattern generation device 1. The pattern generation means generates a vertically compressed (or enlarged) pattern based on the information, and outputs the pattern.
Send to The output device 2 performs printing on the cut sheet based on the input pattern signal.

As a result, data for one continuous sheet can be printed on one page of the cut sheet. Therefore, as shown in FIG. 3, the data of the first line of the page is the same for the cut sheet and the continuous sheet.

Embodiment 2 Next, a second embodiment according to the present invention will be described with reference to FIGS. 2, 4 and 5. FIG. FIG. 2 shows the second data output device.
It shows an embodiment, and the same reference numerals are given to those having the same functions as those in FIG. It is also assumed that the print data input to the circuit of FIG. 2 is originally configured for continuous paper.

In the second embodiment, the data to be printed at the head of the continuous paper is printed at the head of the cut paper, and the line interval between the continuous paper and the cut paper is matched. As described above, the record based on the print data is partially deleted. Next, the circuit of FIG. 2 will be described. In FIG. 2, reference numeral 5 denotes a data adding device for sending information on the length of the continuous paper in the vertical direction to the pattern generating device 1.

As an initial stage, the data adding device 5 sends out “virtual page end data” to the pattern generating device 1.
The “virtual page end data” is data indicating the page end of the continuous paper, and is used to identify print data corresponding to the page end of the continuous paper when storing the print data in the page memory of the pattern generating apparatus. Data.
The pattern generation device 1 sends a pattern signal to the output device 2 based on the “virtual page end data”. The processing operation of the pattern generation device 1 will be described with reference to the flowchart of FIG. The pattern generating apparatus 1 includes a page memory capable of storing at least print data corresponding to one page of continuous paper. Step 1
, The print data is sequentially input for each line, and is sequentially stored in the page memory. In step 2, it is determined whether or not the stored print data has exceeded the virtual page end, that is, whether or not print data corresponding to one page of continuous paper has been stored. If the storage has not been completed, the process returns to step 1 to continue the storage operation. In step 2, if the stored print data exceeds the virtual page end, the process proceeds to step 3, where the print data for one page of continuous paper stored so far is developed into a dot pattern and sent to the output device 2 as a video signal. I do. Thereafter, in step 4, the print data storage position is reset, and the preparation for storing the print data corresponding to the next page to be inputted later at the head of the page memory is completed. The output device 2 inputs the pattern signal output in step 3 and records an image on the cut sheet. However, the pattern signal corresponding to the end of the cut sheet to the end of the virtual page is not recorded on the cut sheet. It will not be recorded.

Embodiment 3 Next, a third embodiment of the present invention will be described with reference to FIGS. 2, 6, and 7. FIG. The third embodiment eliminates the inconvenience of the second embodiment, that is, the inconvenience of lacking a part of data (rows 1-4, rows 2-3, etc.) as shown in FIG. Things.

In the third embodiment, the configuration is such that “virtual page end data” and “real page end data” are transmitted from the data addition device 5 to the pattern generation device 1. The “real page end data” is data indicating the end of the cut sheet used by the output device 2 and corresponds to the page end of the cut sheet when print data is stored in the page memory in the pattern generating device 1. This is data for identifying print data.

The processing operation of the pattern generation device 1 will be described with reference to the flowchart of FIG. In step 1, print data is sequentially input for each line, and is sequentially stored in the page memory. In step 2, it is determined whether or not the stored print data has exceeded the actual page end, that is, whether or not the print data corresponding to one page of the cut sheet has been stored. If the storage has not been completed, the process returns to step 1 to continue the storage operation. In step 2, if the stored print data exceeds the end of the actual page, the process proceeds to step 3, where the print data for one page of the cut sheet stored so far is developed into a dot pattern and output to the output device 2 as a video signal.
Send to Thereafter, in step 4, print data is further input, and it is determined whether or not the stored print data has exceeded the virtual page end (step 5). If the print data stored in step 5 exceeds the virtual page end, the process proceeds to step 6, where the print data from the real page end to the virtual page end is developed into a pattern signal and transmitted to the output device 2. Thus, the output device 2 can record the print data from the real page end to the virtual page end on the next cut sheet.

Thereafter, in step 7, the print data storage position is reset, and the preparation operation for storing the input print data again in the page memory is completed.

By performing the above processing operations, the recording state of the cut sheet output from the output device 2 is as shown in FIG.

That is, in the second embodiment, the print data corresponding to the rows 1-4 and the rows 2-4 is not recorded, but
