DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus,
In particular, the present invention relates to an information processing apparatus to which a printer is connected as an output device.

[0002]

2. Description of the Related Art Conventionally, an information processing apparatus can only confirm that output of a printer output to a printer buffer has been completed, and cannot determine whether or not the printer apparatus has actually performed print output.

[0003]

In the above-mentioned information processing apparatus, it is not possible to confirm whether or not the printout is actually output to the printer device. Therefore, even if the operator goes to get the printout, the printout is still output to the printer. There was not.

[0004]

According to the present invention, in an information processing apparatus to which a printer is connected, print data is transmitted to a printer buffer of the printer, and a printer output end signal transmitting means provided in the printer is transmitted. Receiving the printer output end signal, the display means displays the end of the printer output, and the printer output end signal transmitting means searches for a carriage return code for the contents of the printer buffer and edits the contents up to the searched carriage return code. The printer output end signal is output when an unprocessed carriage return code is lost.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. In the present embodiment, the information processing apparatus 1 is provided with a printer output end display unit 8 and an interface unit 9,
Interface part 9 of information processing apparatus 1 and printer 2
Are connected by a bidirectional data bus 3, a strobe signal 4, an ACK signal 5, and a printer output end signal 6. FIG.
Is a detailed flowchart of the printer output end signal transmitting means 7.

An information processing apparatus having a printer output confirmation function according to this embodiment will be described step by step.

[0008] The information processing device 1 outputs print data to the printer 2 to the bidirectional data bus 3 via the interface unit 9. Whether or not data has been sent to the bidirectional data bus 3 can be determined based on whether or not the strobe signal 4 has been turned on. The printer 2 outputs the strobe signal 4
When the data is turned on, loading of data into the printer buffer 10 is started. When all the data on the bidirectional data bus 3 has been captured, the printer 2 returns an ACK signal 5 to the information processing device 1. This process is repeated until the print data of the information processing apparatus 1 runs out.

The print data for one line is stored in the printer buffer 1.
When the value is set to 0, the printer 2 starts printing and activates the printer output end signal transmitting means 7. The printer output end signal transmitting means 7 searches for a carriage return code from the contents of the printer buffer 10 (step 2).
1) Edit one line from the start of the search to the carriage return code (step 22). Edit the data
Print out (step 22). When the output is completed, the printer buffer 10 is searched again (step 21), and the same operation is performed up to the next carriage return code (step 22). This operation is repeated until there is no unprocessed carriage return code in the printer buffer 10 (step 23).

Triggered by the absence of unprocessed carriage return codes in the printer buffer 10,
The printer output end signal transmitting means 7 transmits the printer output end signal 6 to the information processing device 1.

When the information processing apparatus 1 receives the printer output end signal 6, it activates the printer output end display means 8. The printer output end display means 8 converts the printer output end signal 6 to a screen output code by a predetermined conversion logic, and outputs the printer output signal to a predetermined place on the screen through a bus in the information processing apparatus 1. Is output to indicate that has been completed.

The operator knows from the screen output code display that the printing on the printer has been completed, and does not wait in front of the printer if he or she goes to obtain the printing result thereafter.

[0013]

As described above, according to the present invention, since it is possible for the operator to go to the print device after confirming whether or not the output has actually been made to the printer, the printer is wasted waiting for the output of the printer in front of the printer. There is an effect that time can be eliminated.

Claims (1)

(57) [Claims] An information processing apparatus to which a printer is connected sends print data to a printer buffer of the printer, and receives a printer output end signal sent by a printer output end signal transmitting means provided in the printer. The display means displays the end of the printer output, and the printer output end signal transmitting means searches for the carriage return code for the contents of the printer buffer, edits and prints the contents up to the searched carriage return code, and prints the unprocessed carriage. An information processing apparatus for outputting the printer output end signal when a return code is lost.
