The operation and effect of the manual cut control described above will be described. As described above, the control unit 50 temporarily stops the print job when receiving the ON signal of the manual cut switch 64 as the "first trigger" from the outside, and then manually cuts the print job as the "second trigger". When receiving the ON signal of the switch 64, the auto cutter 4 is driven to roll the roll paper PR.
It has a "special cutting mode" for cutting a cut position C, which is a predetermined "first cutting position".
₁ and a cutting position C ₂ as a “second cutting position”, or an arbitrary position between the other cutting positions.

Here, the controller 50 controls the transport drive roller 19
Once the paper feed direction position of the roll paper P _R at the time of stopping the rotation of a, change and feed forward output signal of the rotary encoder 71 button 63a and the reverse feed button 63
It has a "paper feed reference position storage means" for storing by monitoring which one of b has been pressed, and further returns to the paper feed reference position by rotationally driving the transport drive roller 19a after cutting "return". Mode ". Therefore, the feeding drive roller 19a is temporarily stopped, and then the fine feed button 6 is pressed to adjust the cutting position.
3 also rotates the transport driving roller 19a by operating the roll paper P _R can be resumed again printing operation because the precisely returned to its original position, also the cutting position C that had been originally planned It is possible to perform accurate cutting at ₂ or the cutting position C ₃ . That is, it is possible to freely cut at any place without discarding the print job and the cut job.

The above-described processing from step S301 to step S305 is an optional component for preventing the deterioration of print quality, and the effect of the present invention, that is, the print job and the cut job, can be performed without executing them. It is possible to obtain the effect that the job can be freely cut at any place without discarding it.

[0043]

According to the present invention, the paper feed reference position storage means for storing the paper feed direction position of the recording material as the reference position when the drive control of the carry roller is once stopped, and after the special cut mode is executed. A return mode is provided in which the conveyance roller is drive-controlled to return the recording material to the paper feed reference position. Therefore, even if the conveying roller is temporarily stopped and then the conveying roller is manually rotated to adjust the cutting position of the recording material, and thereby the recording material is displaced from the paper feeding reference position, By executing the return mode, the recording material is returned to the paper feed reference position. Therefore, by restarting the print job from this state, it is possible to continue the interrupted print job and cut job. Become.

That is, the print job and the cut job are temporarily interrupted, and the position other than the position where the recording material is initially cut by using the auto cutter (between the first cutting position and the second cutting position) is cut. Even if it is cut at the position (1), the subsequent cut job is not canceled, and it is possible to obtain the effect that the cutting can be performed at the planned cutting position (second cutting position).
