Printing device and printing method

A printing device comprising

• a printer including a printing head to print a printing subject on a printing medium;
• a transporter including a roller to, while pressing the printing medium against the printing head, transport the printing medium in a feeding direction and a retracting direction;
• and
• a presser to,
• when the printing medium is transported in a feeding direction, cause the roller to press the printing medium against the printing head with first pressure, and
• when the printing medium is transported in a retracting direction, cause the roller to press the printing medium against the printing head with second pressure different from the first pressure,
• wherein
• the presser includes a cam including a first cam surface and a second cam surface, a cam follower moved by the cam, a roller support to support the roller, and an elastic body arranged between the cam follower and the roller support,
• when the first cam surface presses the cam follower, the cam follower presses the elastic body, the roller support is biased by the elastic body, and the roller presses the printing medium against the printing head with the first pressure, and
• when the second cam surface presses the cam follower, the cam follower presses the elastic body, the roller support is biased by the elastic body, and the roller presses the printing medium against the printing head with the second pressure.

A printing device comprising:

• a printer including a printing head to print a printing subject on a printing medium;
• a transporter including a roller to, while pressing the printing medium against the printing head, transport the printing medium in a feeding direction and a retracting direction;
• a presser to,
• when the printing medium is transported in a feeding direction, cause the roller to press the printing medium against the printing head with first pressure, and
• when the printing medium is transported in a retracting direction, cause the roller to press the printing medium against the printing head with second pressure different from the first pressure;
• a cutter to cut the printing medium;
• and
• a tape guide arranged at a location on a forward side in a feeding direction of the roller and in a vicinity of the roller and configured to prevent the printing medium from bending;
• wherein the presser, in response to the cutter having cut the printing medium, causes the roller to press the printing medium against the printing head with the second pressure, and
• wherein, when the cutter cuts the printing medium, the transporter transports the printing medium in a retracting direction and arranges a tip portion of the printing medium on which printing is to be performed at a location between the tape guide and the cutter and in a vicinity of the tape guide.

A printing method for performing printing using a printing device including:

• a printer including a printing head to print a printing subject on a printing medium;
• and
• a transporter including a roller to, while pressing the printing medium against the printing head, transport the printing medium in a feeding direction and a retracting direction,
• the printing method comprising:
• when the printing medium is transported in a feeding direction, causing the roller to press the printing medium against a predetermined portion of the printing head with first pressure;
• and
• when the printing medium is transported in a retracting direction, causing the roller to press the printing medium against the same predetermined portion the printing head with second pressure different from the first pressure, whereby the presser causes the roller to press the printing medium against the same predetermined portion of the printing head with both the first pressure and the second pressure.
