Printing apparatus and method for producing printed matter

1 . A printing apparatus comprising:

a printing unit configured to perform printing on a medium at a printing position in the printing unit;

a conveyance unit configured to convey the medium along a conveyance path;

a winding unit configured to wind up the medium; and

a processor configured to

determine whether a leading end of the medium reaches a predetermined range during conveyance of the medium while the printing is being performed,

determine whether the leading end of the medium reaches a predetermined position disposed downstream relative to an upstream end of the predetermined range along the conveyance path during the conveyance of the medium while the printing is being performed, with the predetermined position corresponding to a position of the leading end of the medium when a break of a printed image on the medium reaches the printing position in the printing unit, and

stop the conveyance of the medium in response to determining that the leading end of the medium reaches the predetermined position after determining that the leading end of the medium reaches the predetermined range, wherein

when the processor stops the conveyance, lower end processing is executed on a printed image adjacent upstream to the break, and upper end processing is executed on a printed image adjacent downstream to the break.

2 . The printing apparatus according to claim 1 , wherein

the processor is configured to stop the conveyance when executing a job requiring winding in the winding unit, and

the processor is configured not to stop the conveyance when executing a job not requiring the winding in the winding unit.

3 . The printing apparatus according to claim 1 , wherein

the processor is configured to stop the conveyance before winding is performed by the winding unit at a timing when the leading end of the medium reaches a stopping position, and

the processor is configured not to stop the convey ance when the winding is already performed by the winding unit at the timing when the leading end of the medium reaches the stopping position.

4 . The printing apparatus according to claim 1 , wherein

the processor is configured to stop the conveyance when a user sets that a stop operation to stop the conveyance by the processor is required, and

the processor is configured not to stop the convey ance when the user sets that the stop operation to stop the conveyance by the processor is not required.

5 . The printing apparatus according to claim 1 , wherein

when the break reaching the printing position is not present while the leading end of the medium is within a predetermined stopping range, the processor is configured to reduce a conveyance speed of the medium by the conveyance unit.

6 . The printing apparatus according to claim 5 , wherein

a downstream end of the predetermined stopping range is an installation floor surface.

7 . The printing apparatus according to claim 5 , wherein

when the break reaching the printing position is not present while the leading end of the medium is within the predetermined stopping range, the processor is configured to reduce the conveyance speed at a timing when the leading end of the medium reaches the upstream end of the predetermined range.

8 . The printing apparatus according to claim 1 , wherein

the break is an area in which printing is not performed over an entire area in a main scanning direction.

9 . The printing apparatus according to claim 8 , wherein

the break is located between a lower end of a printed image in a first printing page and an upper end of a printed image in a second printing page.

10 . The printing apparatus according to claim 8 , wherein

when at least two printed images are disposed to be separated from each other in a conveyance direction of the medium in a same page, the break is located between the at least two printed images.

11 . A method for producing a printed matter by performing printing on a medium using a printing apparatus, the printing apparatus including a printing unit configured to perform printing on the medium at a printing position in the printing unit, a conveyance unit configured to convey the medium along a conveyance path, and a winding unit configured to wind up the medium, the method comprising:

determining whether a leading end of the medium reaches a predetermined range during conveyance of the medium while the printing is being performed,

determining whether the leading end of the medium reaches a predetermined position disposed downstream relative to an upstream end of the predetermined range along the conveyance path during the conveyance of the medium while the printing is being performed, with the predetermined position corresponding to a position of the leading end of the medium when a break of a printed image on the medium reaches the printing position in the printing unit, and

stopping the conveyance of the medium in response to determining that the leading end of the medium reaches the predetermined position after determining that the leading end of the medium reaches the predetermined range, wherein

upon stopping the conveyance, lower end processing is executed on a printed image adjacent upstream to the break, and upper end processing is executed on a printed image adjacent downstream to the break.
