Abstract

PURPOSE:To make the automatic setting to the position in the interruption of printing at the re-insertion of medium and the continuation of printing possible even when printing action is interrupted and the medium is delivered. CONSTITUTION:The printer concerned has a sensor 4, which detects the initial line position of printing of medium 3, a switch 5 for telling the interruption of printing action, a movement detecting means 6 for respectively calculating the movement (a) of the medium and the movement (b) of a printing head and a memory for temporarily memorizing the movement (a) of the medium, the movement (b) of the printing head and received and un-printed data.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printer with a front inserter mechanism, and more particularly to a printer capable of interrupting printing even during a printing operation.

[0002]

2. Description of the Related Art A conventional printer prints all print data on a medium and then ejects the medium when a printing operation is started.

[0003]

In the above-mentioned conventional printer, if the printing is interrupted during the printing operation of the received print data, all the print data that has been received up to that point will be cleared. If you try to check the print status up to that point, the print operation will be interrupted and the print status will be checked after ejecting the medium.After checking, insert a new medium and start printing from the beginning. There was a problem that it did not happen.

[0004]

SUMMARY OF THE INVENTION A printer according to the present invention comprises a medium movement amount from the time when the sucked medium is set at the printing first line position to the present, a print head movement amount from the home position to the present, and printing. The unprinted data that was received at the time of the operation interruption is stored respectively.
It is set automatically at the same position as when interrupted so that printing can continue.

[0005]

According to the present invention, the printing can be temporarily interrupted during the printing operation, and the medium can be ejected to check the printing state.

1 is a block diagram showing an embodiment of a printer according to the present invention. At the same time, 1 is, for example, FIG.
Received print data “012-XYZ” shown in (A)
Is stored in the print buffer, 2 is a printing means for printing the received print data stored in the print buffer 1 on the medium 3, 4 is a sensor for detecting the print first line position, and 5 is an instruction to interrupt the printing operation. A switch 6 is a medium movement amount a from the print first line position of the medium 3 to the current print position (see FIG. 2B).
Print head movement amount b from the print head home position to the current print position (see FIG. 2B).
Is a movement amount detecting means for calculating and outputting.

Reference numeral 7 denotes a medium movement amount a and a print head movement amount b calculated by the movement amount detection means 6 when the switch 5 is pressed in the printing operation, for example, in the state shown in FIG. Print data "DEF ~ XYZ"
As shown in (C), the memory for temporarily storing the medium 8 automatically ejects the medium 3 when the switch 5 is pressed down, and then shifts to the suction monitoring state, and the ejected medium 3 is again detected. When it is inserted, the insertion is detected and a medium insertion detection signal is output to the memory 7, whereby the medium movement amount a and the print head movement amount b stored in the memory 7 are read out, and the medium 3 and the printing means 2 are set. It is an intake / exhaust unit that is reset to the position before the switch 5 is pressed.

Next, the operation of the printer having the above structure will be described with reference to FIGS. First, the medium 3 is set in the printer, and the print buffer 1 shown in FIG.
Received print data “012-XYZ” shown in (A)
Is set. Then, printing is started, and as shown in FIG.
As shown in (B), when the print data “C” is printed during printing, the switch 5 is pressed. Therefore, the movement amount detecting means 6 calculates the medium movement amount a from the print first line position to the current print position and the print head movement amount b from the home position of the print head to the current print position, as shown in FIG. It is stored in the memory 7 as shown in C).

Then, the suction / discharge means 8 automatically discharges the medium 3 and then shifts to the suction monitoring state. And
After confirming the printing state, when the medium 3 is inserted into the suction / discharge means 8, the suction / discharge means 8 sets the medium 3 on the first print line detected by the sensor 4, and then the medium stored in the memory 7. The medium 3 is sent by the movement amount a. Then, the printing unit 2 moves the print head by the print head moving amount b stored in the memory 7. Then, when the received unprinted data "DEF to XYZ" is printed, as shown in FIG. 3, it is possible to print again at the print position where the printing in the state at the time of the print interruption is continued.

[0010]

As described in detail above, the printer according to the present invention is capable of interrupting printing during the printing operation, and moreover, the print line position of the medium, the position of the print head at the time of interrupting the printing operation, By storing the unprinted data and the unprinted data, even if the medium is ejected during the printing operation, it is possible to automatically return to the state where the printing was interrupted again, and it is possible to continue printing. is there.
