a sensor carried on the carriage at a position in the first direction between the head and the end of the carriage where the sensor is capable of facing the platen and a medium supported by the platen, the sensor being configured to detect the medium supported by the platen;

a liquid receiver disposed at a position in the first direction between the head and an end in the first direction of the platen where the liquid receiver is capable of facing the nozzles, the liquid receiver configured to receive a liquid discharged from the nozzles; and

a controller configured to control, based on printing data, the head and the carriage to repeat conveyance of a medium by use of the conveyer and a printing pass in which the liquid is discharged from the nozzles during movement of the carriage,

wherein in a case that the controller has received printing data to be printed on a plurality of mediums and that printing data for a next medium of a certain medium, which is currently subjected to printing, is present, the controller is configured to execute flushing, in which the liquid is discharged from the nozzles toward the liquid receiver, after executing printing in a certain printing pass, which is executed before a last printing pass for the printing on the certain medium and during which the carriage moves in the first direction, and

wherein in a case that the controller has received printing data to be printed on the plurality of mediums and that printing data for the next medium of the certain medium, which is currently subjected to printing, is present, the controller is configured not to execute the flushing at timing between the last printing pass for the printing on the certain medium and a first printing pass for printing on the next medium.

2. The printing apparatus according to claim 1 , wherein, in a case that the carriage moves in the first direction in the last printing pass for the printing on the certain medium, the controller is configured to move the carriage in the second direction at the timing between the last printing pass for the printing on the certain medium and the first printing pass for the printing on the next medium, and

in a case that the controller has determined, based on an output result of the sensor, during movement of the carriage before the liquid is discharged in the first printing pass for the printing on the next medium, that a medium is supported by the platen, the controller is configured to continue the printing in the first printing pass without stopping the movement of the carriage.

3. The printing apparatus according to claim 2 , further comprising a tray configured to accommodate a medium; and

a feeder configured to feed a medium accommodated in the tray to the conveyer,

wherein, in the case that the carriage moves in the first direction in the last printing pass for the printing on the certain medium, the controller is configured to control the feeder to feed a medium accommodated in the tray while moving the carriage in the second direction at the timing between the last printing pass for the printing on the certain medium and the first printing pass for the printing on the next medium.

4. The printing apparatus according to claim 2 , wherein, in a case that the controller has determined, based on the output result of the sensor, during the movement of the carriage before the liquid is discharged in the first printing pass for the printing on the next medium, that a medium is not supported by the platen, the controller is configured to cancel the printing on the next medium.

5. The printing apparatus according to claim 2 , further comprising an annunciator,

wherein the controller is configured to cause the annunciator to inform a user of information, in a case that the controller has determined, based on the output result of the sensor, during the movement of the carriage before the liquid is discharged in the first printing pass for the printing on the next medium, that a medium is not supported by the platen.

6. The printing apparatus according to claim 1 , wherein, in the certain printing pass, the controller is configured to move the carriage to a facing position, in which the carriage faces the liquid receiver, without reducing a carriage moving speed after executing printing on a medium.

7. The printing apparatus according to claim 1 , wherein, in a case that the controller has determined, based on the printing data, that the printing data for the next medium of the certain medium is present and in a case that the carriage moves in the second direction in the last printing pass, regardless of a position of an end in the second direction of an area to be printed, the controller is configured to move, in the last printing pass, the carriage to a first position where the sensor faces a downstream end in the second direction of the next medium or a second position positioned downstream of the first position in the second direction, without reducing a carriage moving speed after executing printing on a medium.

8. The printing apparatus according to claim 1 , wherein the certain printing pass is a printing pass executed immediately before the last printing pass, among a plurality of printing passes to be printed on the certain medium, during which the carriage moves in the first direction.

9. The printing apparatus according to claim 1 , wherein a discharge amount of the liquid from each of the nozzles in the flushing executed in the certain printing pass is larger than a discharge amount of the liquid from each of the nozzles in flushing executed in a printing pass executed before the certain printing pass for the printing on the certain medium.

10. The printing apparatus according to claim 1 , wherein the sensor is an optical sensor configured to optically detect the medium supported by the platen.

11. A printing apparatus, comprising:

a conveyer configured to convey a medium in a conveyance direction;

a head having a nozzle surface in which a plurality of nozzles are formed;

a carriage carrying the head and configured to move in a first direction, which is parallel to the nozzle surface and intersects with the conveyance direction, and a second direction, which is opposite to the first direction,

a platen disposed in a position downstream of the conveyer in the conveyance direction where the platen faces the nozzle surface, configured to support a medium, and including a liquid receiver disposed in a position where the liquid receiver is capable of facing the nozzles, and configured to receive a liquid discharged from the nozzles;
