They are mutually connected via a bus line 10 composed of a data bus and a control bus.

The RAM 3 is provided with a reception buffer 11, and the reception buffer 11 is adapted to store print data received from the host device connected to the external interface 9 via the interface 9.

The paper feed controller 4 is connected to a paper feed mechanism 12 including a pulse motor for driving a print medium 21 described later along a platen (not shown), and the carrier controller 5 is connected to the platen along the platen. A carrier 13 provided so as to be movable in the line direction is connected, and the carrier 13 is connected to the print controller 6.
The print head 14 mounted on the carrier 13 is connected to the print head 14, and the bar code controller 7 is connected to the bar code reader 15 mounted on the carrier 13.

The print head 14 and the bar code reader 15 are arranged side by side on the carrier 13, as shown in FIG.

FIG. 3 shows the structure of the print medium 21.
On this print medium 21, a top bar code A is printed on the leftmost top position which is a predetermined distance X from the front end thereof, and a plurality of intermediate bar codes B corresponding to each print line except the last print line underneath. Is printed, and the end barcode C is printed corresponding to the final print line.

The first bar code A and the intermediate bar code B have information on the feed amount to the next print line and the print start position of the next print line, and the end bar code C has print end information. ing.

Each of the bar codes A, B, and C is the bar code reader 1 when the carrier 13 is at the leftmost position.
It is printed at a position where it can be read at step 5.

The print medium 21 is attached to the I / O port 8.
A paper end sensor 17 for detecting the presence or absence of is connected. The paper end sensor 17 is the print head 1
It is provided in front of 4.

When the print medium 21 is inserted and set, the CPU 1 carries out the print control shown in FIG.

First, in ST1, the paper feeding mechanism 12 is
Is controlled to feed the inserted print medium 21. Then, at ST2, the paper end sensor 1
When the print medium 21 is detected by 7 in step ST3, the print medium 21 is further moved from that position by a predetermined pulse, that is, the distance X.
Only feed. As a result, the barcode reader 15 is positioned at a position where the leading barcode A can be read.

Subsequently, in ST4, the bar code reader 1
The leading bar code reading calculation operation according to 5 is performed.

In this reading calculation operation, as shown in FIG. 5, the leading bar code A is read in ST11, and S
The leading bar code A read at T12 is analyzed to calculate the feed amount to the next print line. Then, in ST13, the print start position of the next print line is calculated.

When the leading bar code reading calculation operation in ST4 is completed, the paper feeding mechanism 12 is driven based on the feed amount to the next print line calculated in ST5 to feed the print medium 21. . (Feed control means) At this time, since the bar code reader 15 is positioned at a position where the next bar code can be read, the bar code reading calculation is performed in ST6, and the printing obtained by the previous bar code reading is performed. The carrier 13 and the print head 14 are driven based on the start position to perform the printing operation. (Printing means) That is, in the barcode reading calculation and printing operation, as shown in FIG. 6, first, in ST21, the barcode reader 15 reads the corresponding barcode. Subsequently, in ST22, one line of the print data stored in the reception buffer 11 is developed into a dot pattern in the RAM 3 based on the calculated print start position. Then, based on the developed dot pattern, the carrier 13 and the print head 14 are driven in ST23 to print data on the corresponding print line.

Subsequently, the read bar code is analyzed in ST24, and if the bar code is the intermediate bar code B, the feed amount to the next print line is calculated. Further, in ST25, the print start position of the next print line is calculated.

Upon completion of the bar code reading calculation and printing operation in ST6, it is determined in ST7 whether the bar code read in ST6 is the end bar code C or not. When the bar code is the intermediate bar code B, the control is returned to the feed control of ST5, and when the bar code is the end bar code C, the printing operation is ended and the print medium 21 is ejected.

In the present embodiment having such a structure, the bar code is printed on the print medium 21 corresponding to each print line based on the print format.

When such a printing medium 21 is inserted and set and the printing operation is started, first, the printing medium 21 is fed by the paper feeding mechanism 12, and when the paper end sensor 17 detects the leading end of the printing medium 21, its position. Then, the print medium 21 is further fed by the distance X, and then the feeding is stopped.

As a result, the first barcode A is read and analyzed by the barcode reader 15. By analyzing the head bar code A, the feed amount a to the next print line and the print start position d of the next print line can be obtained.

In this way, the print medium 21 is fed by the paper feeding mechanism 12 by the distance a. With this feed, the barcode reader 15 is now the first intermediate barcode B.
Reach the reading position and read the bar code. In this way, the first intermediate bar code B is analyzed and the feed amount b to the next print line and the print start position e of the next print line are obtained.

Then, based on the print start position d obtained by analyzing the leading bar code A read last time, the first 1
The print data of the line is developed into a dot pattern, the carrier 13 and the print head 14 are driven, and the first line is printed on the print medium 21.

When this printing is completed, this time the print medium 2
1 is fed by the paper feed mechanism 12 by a distance b. By this feed, the bar code reader 15 reaches the position where the second intermediate bar code B is read this time, and reads the bar code. Thus the second intermediate bar code B
Is performed to obtain the feed amount c to the next print line and the print start position f of the next print line.

Then, the print data of the second line is developed into a dot pattern based on the print start position e obtained by the analysis of the first bar code B read last time, and the carrier 1
3 and the print head 14 are driven to print the second line on the print medium 21.

When this printing is completed, this time the print medium 2
1 is fed by the paper feed mechanism 12 by a distance c. By this feed, the bar code reader 15 reaches the position for reading the third intermediate bar code B this time, and reads the bar code.

Thereafter, the reading analysis of the intermediate bar code B printed corresponding to each printing line in this way and the printing of each line based on the analysis result are repeated.

Finally, when the end bar code C is read and analyzed by the bar code reader 15, the dot pattern data developed based on the print start position obtained by the previous reading and analysis of the intermediate bar code B. The last line is printed, the printing operation is completed, and the print medium 21 is ejected.

In this way, the bar code having the feed amount to the next print line and the print start position of the corresponding print line is printed on the print medium 21, and this bar code is read and analyzed when printing is performed. Since the feed control and the print control are sequentially executed, it is not necessary to perform the operation of designating the format of the print medium for various formats of the print medium, which makes the printing operation easy.

Further, no matter how the format of the print medium is changed, the bar code corresponding to it is changed to the print medium 2
If the data is printed in advance in 1, the data can be printed according to the format without any problem, and the format change can be easily dealt with.

In the above embodiment, the case where the bar code is printed on the left side of the print medium has been described, but it goes without saying that the printing position is not necessarily limited to this.

In the above embodiment, the bar code is
The one that has information on the feed amount to the next print line and the print start position of the next print line, and the one that has print end information have been described, but for example, use the one that has only the feed amount to the next print line. May be.
