Printer

A printer comprising:

• a conveyor configured to convey a medium to be printed along a conveyance path;
• a print head configured to print in a first area of the medium;
• a platen roller disposed on a side opposite to the print head, wherein the conveyance path is interposed between the platen roller and the side opposite to the print head, the platen roller configured to apply a conveying force to the medium by rotating while pinching the medium between the platen roller and the print head;
• an actuator configured to move one of the print head and the platen roller between (i) a first position where the print head and the platen roller pinch the medium and (ii) a second position wherein the print head is spaced from the medium;
• one or more processors operatively coupled to the actuator and configured to:
• operate the actuator in a saving mode wherein the one of the print head and the platen roller is moved to the first position when the first area of the medium to be printed passes through the print head, and the one of the print head and the platen roller is moved to the second position when a second area of the medium passes through the print head;
• detect a difference between:
• a first conveyance amount for the medium to pass through the print head when both (i) the medium is conveyed by the conveyor and (ii) the actuator is operated in the saving mode;
• and
• a second conveyance amount for the medium to pass through the print head when both (i) the medium is conveyed by the conveyor and (ii) the one of the print head and the platen roller is in the first position;
• and
• adjust, based on the difference, a setting corresponding to the first conveyance amount to eliminate the difference between the first conveyance amount and the second conveyance amount.
