FIG. 9 is a block diagram showing the arrangement of a printer 100a according to the second embodiment of the present invention. The parts common to those in FIG. 1 described above are designated by the same reference numerals, and their description will be omitted.
In FIG. 9, the ROM 16a stores various data such as character font data corresponding to a character code, in addition to the control program shown in the flowchart of FIG. A print data buffer 19 stores the font address of the ROM 16a corresponding to the character code included in the received print data.

Next, referring to the flowchart of FIG.
The second embodiment of the present invention will be described in detail. The control program that executes the processing shown in this flowchart is
It is stored in the ROM 16a.

First, in step S71, the data transmitted from the host computer 11 is received, and in step S72
If there is no print data, the process ends. When print data is input, the process proceeds to step S73, and it is determined whether the command is a character modification command. The character modification instruction in this embodiment includes an instruction for designating a character style to be printed, such as emphasized printing, double-width printing, and italic printing. If it is determined that the modification command is a character modification command, the process proceeds to step S73a, and it is determined whether the modification information is different from the character modification information up to that point. If so, the process proceeds to step S74, the character decoration information up to that time is changed according to the newly input character decoration information, and the decoration information change flag is turned on. On the other hand, if it is the same character decoration information, nothing is done and the process returns to step S71.

When a print position moving command is input in step S76, the flow advances to step S77 to change the character print position and set the print position change flag. These flags are set in the RAM 17, and the newly input character modification information or print position movement command is stored in the RAM 1.
It shall be temporarily stored in the work area of 7.
Further, the print position moving command is a command for changing the print position, such as a horizontal tab.

If the command is not a print position movement command in step S76, the process proceeds to step S79 to determine whether it is a character code. If it is not a character code, the process returns to step S71. If it is a character code, the process proceeds to step S80 to check whether the modification information change flag is on, and if it is on, step S
In step 81, the character decoration information stored in the RAM 17 in step S74 is stored in the print data buffer 19,
In step S82, the decoration information change flag is turned off. At this time, the value of the number of characters counted up to that point is stored in the print data buffer 19, and the value of the character number counter is reset to "0".

In step S83, the print position change flag is referred to check whether or not the print position is changed. If the print position change flag is on, that is, if the print position is changed, the process proceeds to step S84, RAM in S77
The print position stored in 17 is the print data buffer 1
9, and the print position change flag is turned off in step S85.

Thus, the process proceeds to step S86, and the ROM 16a in which the character pattern corresponding to the input character code is stored at the next address of the print data buffer 19
The font address (font data position) is set, and the value of the counter for counting the number of characters corresponding to the character modification information is incremented by 1 in step S87.

Next, a specific example of the processing shown in the flowchart of FIG. 10 will be described in detail with reference to FIGS.

In FIG. 11, first, the character code of the character A and its modification information are input and the print data buffer 19 is input.
It is a figure which shows the state stored in. FIG. 12 shows a state in which the character code of the character B is next input in this state, the font address of the character B is stored in the area 120 following the font address of the character A (step S86), and the count value of the number of characters is calculated. Is counted up to "2" (step S87). In addition, following FIG. 11, the code of the letter B,
When the same character decoration information as in the case of the character A is input, the decoration information change flag is not set by skipping from step S73a to step S76.
The result is similar to that shown in FIG. This is shown in Figure 1 below.
4 and FIG. 16 are the same.

FIG. 13 shows the contents of the print data buffer 19 when the character modification information is further input and the character code of the character C is subsequently input. In this case, the modification information change flag is set to ON when the character modification information different from the immediately preceding character modification information is input (step S7).
5) Next, when the character code of the character C is input, it is checked whether or not the modification information change flag is on (step S8).
0). Here, since the modification information change flag is turned on, the character modification information newly input and saved in the RAM 17 (step S74) is stored in the area 121 of the print data buffer 19, and the characters are stored in the area 122. C
The font address of is stored (step S86). FIG. 14 shows a state in which the character code of the character D is input subsequent to the character C. Here, the area 12 next to the area 122 is displayed.
The font address of the character D is stored in 3.

In FIG. 15, the print position moving command is input next,
The case where the character code of the character E is input next is shown. In this case, when the print position movement command is input, the print position change flag is turned on (step S77), and when the code of the letter E is input next, it is determined whether the print position change flag is turned on. (Step S83). Here, because this print position change flag is on,
The print position saved in the RAM 17 is stored in the area 124, and the start address of the character font of the character E is set in the next area 125 (step S86). or,
FIG. 16 shows a case where the character code of the character F is further input after that, and the font address of the character F is stored in the area 126 following the area 125 (step S86).
The count value of the number of characters is incremented to "4".
