Image recording apparatus, computer-readable storage medium, and method for appropriately enlarging image in borderless image recording

A non-transitory computer-readable storage medium storing computer-readable instructions that are executable by a processor of an image recording apparatus, the image recording apparatus comprising a conveyor configured to convey an image recording medium in a conveyance direction, and an image recording engine configured to record an image on the image recording medium, the instructions being configured to, when executed by the processor, cause the image recording apparatus to:

• determine whether a medium length of the image recording medium in the conveyance direction is equal to or less than a particular length;
• in response to determining that the medium length is equal to or less than the particular length, perform a first enlargement process to enlarge the image to a size with a first overhang area by which the enlarged image extends beyond an image recording target area, the first overhang area having an overhang width of a first value in an orthogonal direction that is orthogonal to the conveyance direction;
• in response to determining that the medium length is not equal to or less than the particular length, perform a second enlargement process to enlarge the image to a size with a second overhang area by which the enlarged image extends beyond the image recording target area, the second overhang area having an overhang width of a second value in the orthogonal direction, the second value being smaller than the first value;
• and
• perform an image recording process to control the conveyor and the image recording engine to record, in the image recording target area on the image recording medium, the enlarged image resulting from one of the first enlargement process and the second enlargement process, thereby performing borderless image recording in which there is no margin at a periphery portion of the image recording target area.

A method implementable on a controller of an image recording apparatus, the image recording apparatus comprising a conveyor configured to convey an image recording medium in a conveyance direction, and an image recording engine configured to record an image on the image recording medium, the method comprising:

• determining whether a medium length of the image recording medium in the conveyance direction is equal to or less than a particular length;
• in response to determining that the medium length is equal to or less than the particular length, performing a first enlargement process to enlarge the image to a size with a first overhang area by which the enlarged image extends beyond an image recording target area, the first overhang area having an overhang width of a first value in an orthogonal direction that is orthogonal to the conveyance direction;
• in response to determining that the medium length is not equal to or less than the particular length, performing a second enlargement process to enlarge the image to a size with a second overhang area by which the enlarged image extends beyond the image recording target area, the second overhang area having an overhang width of a second value in the orthogonal direction, the second value being smaller than the first value;
• and
• performing an image recording process to control the conveyor and the image recording engine to record, in the image recording target area on the image recording medium, the enlarged image resulting from one of the first enlargement process and the second enlargement process, thereby performing borderless image recording in which there is no margin at a periphery portion of the image recording target area.
