Printer and printing method which prevents a decurling unit from deteriorating a print quality

A printer that divides a roll recording medium in a length direction to set one printing target range, the printer comprising:

• a conveyance unit configured to nip and simultaneously convey the roll recording medium;
• a print unit configured to print an image by sequentially transferring a plurality of color inks on the recording medium while nipping the recording medium conveyed by the conveyance unit;
• a decurling unit disposed between the conveyance unit and the print unit, and configured to include a raised portion that decurls the recording medium by contacting the recording medium conveyed by the conveyance unit;
• and
• a control unit configured to control the conveyance unit to convey the recording medium to a waiting position after ending the transfer of one color ink,
• wherein the waiting position is a position where an area on a leading edge side of the recording medium is in contact with the raised portion, and
• wherein the waiting position is different within the area on the leading edge side for each of the color inks.
