Printing up to edges of printing paper without platen soiling

A dot-recording device for recording dots on a print medium comprising:

• a dot-recording head provided with a plurality of dot-forming elements for ejecting ink droplets;
• a head driver configured to drive at least part of the plurality of dot-forming elements to form dots;
• a transporting unit configured to transport the print medium in a transporting direction;
• a platen configured to support the print medium at a position opposite the dot-recording head, the platen having an ink accepting portion, a width of the ink accepting portion in the transporting direction corresponding to a specific range of the dot-recording head including part of the plurality of dot-forming elements;
• and
• a controller configured to control the head driver and the transporting unit, wherein
• the controller includes:
• (a) a first recording mode to effect printing near an edge of the print medium, in the first recording mode the controller performing edge printing by ejecting ink droplets from at least some of the dot-forming elements disposed opposite the ink accepting portion, and the edge of the print medium is disposed above the ink accepting portion;
• and
• (b) a second recording mode to effect printing in an intermediate portion of the print medium, a maximum sub-scan feed amount in the second recording mode being greater than a maximum sub-scan feed amount in the first recording mode.

A dot-recording method for recording dots on a print medium up to an edge of the print medium using a dot-recording device, comprising:

• (a) preparing a dot-recording device including:
• a dot-recording head having a plurality of dot-forming elements for ejecting ink droplets;
• and
• a platen configured to support a print medium at a position opposite the dot-recording head, the platen having an ink accepting portion, a width of the ink accepting portion in a transporting direction corresponding to a specific range of the dot-recording head including part of the plurality of dot forming elements:
• (b) in a first recording mode to effect printing near an edge of the print medium, performing edge printing by ejecting ink droplets from at least some of the dot-forming elements disposed opposite the ink accepting portion, and the edge of the print medium is disposed above the ink accepting portion;
• and
• (c) in a second recording mode to effect printing in an intermediate portion of the print medium, performing intermediate printing with a maximum sub-scan feed amount being greater than a maximum sub-scan feed amount in the first recording mode.
