Retrieve each specified information from the DTP switch to set the code system, etc.

Next, we will explain the operation of this embodiment configured in this way. This will be explained with reference to FIG. 6 and subsequent figures.

First, here, the emphasis printing instruction from the host side is ESC.
(escape) sequence, and the emphasis print start (frame start) command I<LJrEsc+]J
So, the command to end emphasized printing (end frame) is rEsc+
It is assumed that each rp can be obtained in 2J.

Therefore, as shown in FIG. 6, the microcomputer 91 performs initial settings to return the printer to its initial state when the power to the printer is turned on or when an initialization command is input from the host side.

After that, RAM9! It is determined whether there is reception data from the host in the reception buffer secured in l, and if there is no reception data, it waits to receive data from the post.

Then, if there is received data in the receive buffer, the received data is read, it is determined whether the received data is print data or not, and if it is not print data, the 5 frame silking start command FrE
SC+1" is determined. Note that this discrimination process is
Actually, if it is not print data, it is determined whether it is ESC or not, and if it is ESC, the next received data is read from the reception buffer, and it is determined whether the received data is "rl" or not.

At this time, if the received data is rEsc+IJ, the framework start flag ■2S and the framework end flag LE are set to "1".
Sera+-(Ls←1.LE4-])j.

and returns to processing the next received data.

Also, if the received data is not rEsc+IJ.

Frame end command r E S C + 2 J determines whether or not it is determined in the same way, and if it is r E S C + 2 J, selects and prints vertically lined characters from the characters on the type wheel 38, and also resets the framework end flag L E ( LE←0), the process returns to the next received data.

Note that if the received data is not rEsc+2J, other ESC and processing are executed, and then the process returns to the next received data.

On the other hand, when the received data read from the receive buffer is print data, it is determined whether the framework start flag L S is i,, S = 1 or not.

When the framework start flags L and S=1, after printing a vertical line, the framework start flag LS is reset by 1-(LS←0). Furthermore, after printing the lower horizontal line of the character and the upper horizontal line of the character, a character corresponding to the content of the print data is printed, and the process returns to the next received data.

Furthermore, when the framework start flag L S = ] is not the case, it is further determined whether the framework end flag L E is I-E = ]. Then, when L E = 1, after printing the horizontal line on the lower side of the character and the horizontal line on the upper side of the character, a character according to the content of the print data is printed, and the process returns to the first received data. When LE = ] is not found, characters corresponding to the contents of the print data are printed as is, and the process returns to the first received data.

Next, this process will be explained with reference to FIGS. 7 and 8.

First, data r is sent from the host side, for example, as shown in FIG.
A,, B, C,...J, 1. Suppose that J is received.

Therefore, since the data "rA, R, C, SP (space)" is print data, these data are printed as they are as rA, B, C, -3PJ. Note that sp is blank.

Then, when the framework start command rEsc+IJ is read, set the 5 framework start flags ■ and S and the framework end flag LE to ``1''.

Therefore, when the data rDJ is subsequently read,
This data rDJ is print data.

Since the framework start flag LS is "1", a vertical line is printed to set the framework start flag LS to "0", then upper and lower horizontal lines are printed, and then the characters rDJ are printed. That is, for the character immediately after the framework start command rESC+1, w and Is@ are printed on the left side of the character, and a horizontal line is printed on the lower side of the character.

Then, when the next data I'EJ is read.

This data rEJ is print data, the framework start flag LS is rQJ, and the framework end flags L, E
is "1", so after printing the upper and lower horizontal lines,
Print the characters rEJ. That is, the framework start command r
For characters after the character immediately after Esc+IJ, horizontal lines are printed at the top and bottom.

Thereafter, in the same way, data rF, SP, G, )1
When ゜■'' is read, horizontal lines are printed above and below each character.

When the framework end command rEsG+2J is read, after printing a vertical line, the framework end flag LE is
Set to "0". In other words, the framework exit command rESC
Print a vertical line to the right of the letter "I" just before +2J.

As a result, both the framework start flag LS and the framework end flag LE become "O" and the framework mode is canceled, so that the subsequent data rSP, J.

K and LJ are printed as they are.

This results in the character string "D" as shown in FIG.

E, F, SP, G, H, and TJ are surrounded by a frame and are emphasized more than other characters.

In this manner, this printer has a function of printing a frame surrounding a designated character or character string when receiving an emphasis printing instruction from the host side, thereby increasing the character emphasis printing function.

And when you want to emphasize the text by surrounding it with a frame like this,
The burden on the host side is lightened because a frame surrounding the specified character is printed by simply giving a frame start command and a frame end command without having to add data for vertical lines and horizontal lines and send them from the host side.

In the second embodiment, an example in which the present invention is applied to a type wheel type printer has been described, but other examples, such as a dot impact printer, may also be used.

The present invention can be similarly applied to various printers such as thermal printers, thermal transfer printers, inkjet printers, optical printers, and light emitting diode printers, and printing devices such as electronic typewriters.

Processing As described above, according to the present invention, the printer's emphasis printing function can be made multi-functional.
